LEADING MOTORMAN ATKINS TATTENHAM CORNER



D. McMULLEN, Colonel. 

f the accident which occurred at approximately10.42 a.m . on Sunday, 24th July, 1949, at London Bridge Station in the Southern 

Region, British Railways. A light engine, which had been authorised to leave No. 10 low level platform on the Down Through 

line, ran past a signal at Danger and collided almost head on at a combined speed of about 15 m.p.h. with the 9.48 a m electric 

train from Tattenham Corner to Charing Cross which was passing from the Up Through line of the Central Section to No. 1 Up 

line of the Eastern Section. The train was carrying between 80 and 100 passengers, of whom 11 complained of injury or shock, 

and 3 were taken to Guys Hospital. The motorman of the passenger train and the driver and fireman of the light engine were 

also removed to hospital; the passengers and the motorman were not detained and the driver and fireman were discharged after 

three days.

The collision took place on a viaduct. First aid to the injured was rendered by a doctor who was a passenger in the Tattenham 

train and also by railway staff from London Bridge Station. Ambulances were called with commendable promptitude, two 

arriving in the street below within fifteen minutes; however, in view of the difficulty in moving the injured to the ambulances, 

an empty electric train was run to the site on an adjacent line, and the passengers and injured were loaded into it and taken to 

London Bridge Station, where the ambulances, which had been redirected, were waiting. The accident caused considerable 

dislocation to traffic ; 44 trains were cancelled and the working of 42 others was altered.

The passenger train was a four coach all steel close-coupled suburban set with a motor coach in front and in rear and two 

trailing coaches in the centre ; it was driven from theleft handside. Brake power was 59% of the total weight of 142 tons ; the 

brake blocks on the driving bogies were of cast iron and of non-ferrous material on all other wheels. The light engine, which 

was travelling chimney first, was a " C " class 0-6-0 right hand drive freight engine with a six-wheeled tender ; the vacuum 

brake operated on all wheels and its power was 26% of the total weight of 82 tons.

The engine struck the centre of the driving compartment of the leading motor coach and was derailed. The main frames of the 

engine were badly buckled and other damage, mainly at the front end, was sustained. The driving bogie of the motor coach was 

displaced and the front end was heavily damaged.

No arcing occurred and there was no fire ; the current was cut off without delay. There was no damage to the track. The engine 

was rerailed and normal working was resumed at 7.30 p.m.

It was a fine sunny day.

2. The relevant features of the layout, signals and track circuits at London Bridge are shown in the sketch. The approach to the 

Home signals, over the Up Through line, is straight as also is the line from No.10 platform on to the Down Through. Gradients 

are negligible

The view of signals Nos. 156 and 157 is good, it being possible to see the former from Platform No. 10 and the latter from a 

point on the Down Through line opposite the signal box. The complicated layout and the intensity of traffic at London Bridge 

has necessitated the acceptance of reduced overruns ; normally this is not less than 200 yards but beyond signal No. 157 it is 

103 yards.

Signals and points are controlled from one large signal box containing a Westinghouse electric power frame with 277 miniature 

working levers. The levers are interlocked mechanically and track circuits operate electric controls. Red, yellow and green hull’s 

eye lights immediately above the miniature levers repeat the aspect of the signal. Two large illuminated diagrams (duplicates) 

are provided in the box. Trains are worked by block bells and train describers. 

EVIDENCE

4. The Sunday morning serviceswere being worked normally and trains were running on time. Inspector S. Jones, who was on 

duty in the signal box at London Bridge, saw the light engine, which had arrived at No. 10 Low Level platform a t 10.33 a.m. 

from North Kent (East) Junction, and was informed that it was bound for New Cross Gate on the Down Through line. Shortly 

afterwards he noticed from the diagram that track circuit No. 98 on that line became clear ; he realised that the light engine must 

have passed signal No. 157 at Danger as at the same time he saw track circuit No. 103 occupied by the Tattenham train, which 

he knew was approaching on the Up Through line and would pass over crossover No. 260. It was evident that a collision would 

occur. He immediately examined the frame and saw signal levers Nos. 156 and 157 were normal with their indication lights at 

red ; he also saw levers Nos. 260 and 261 were reversed. He stated that the levers of all signals on the Down Local line were 

normal and that the last train over that line had left from No. 13platform at 10.35 am.

Inspector Jones went on to say that no questlon was raised regarding preference to either the passenger train or the light engine 

over the diamond crossing ; if there had been any discussion on this point it would have been referred to him. He explained that 

as crossover No. 260 had been reversed for the passenger train, signal lever No. 157 was locked normal ; also that had lever No. 

157 been pulled before the crossover had been reversed, then the signal lever could not have been replaced to normal after 

approach track circuits Nos. 97A and 98 had been occupied, until they had been cleared or until the lineman had given a back-

lock release (which bad not been done), and hence lever No. 260 could not be reversed.

Inspector Jones had been at London Bridge for 10 years and he had no knowledge of any recent signal or point failure in the 

vicinity of signal No. 157 ; he recalled that the few failures which had occurred else- where were all safety side failures. He said 

he was present when the lineman tested the relevant electrical circuits at about 11.30 a.m. and also when the mechanical locking 

was tested later, and that both tests revealed that everything was in order.

5. Signalman F. A. Kenward was in charge of the eastern section of the frame. He was advised of the Tatenham train by 

Signalman Beach, in charge of the central section, and when he saw track circuit No. 102 become occupied, he set the road for 

the train by drawing levers Nos. 260 and 261, the indication light above the latter changing to Yellow. At the time he was not 

aware that there was a light engine on No. 10 platform to go along the Down Through. He drew lever No. 259 after track circuit 

No. 99 became occupied and the indication turned to Yellow. The first he knew of anything being wrong was when Inspector 

Jones saw from the diagram that the light engine had passed signal No. 157. Kenward said that at that time levers Nos. 259,260 

and 261 were drawn, signal No. 259 was still showing Yellow and No. 261 had turned to Red as soon as the train had passed it. 

He could not see the position of levers Nos.156 and 157 as they were some way from where he was standing.

6. Signalman A. V. Beach said that the Tattenham train was described to him at 10.39 a.m. and he informed Kenward who 

would signal the train. Shortly afterwards the driver of a light engine telephoned from No. 10 platform saying that the engine 

was for New Cross. Beach replied " all right, you will be going down the Through " and then pulled levers Nos. 197, 141 and 

156 for it to proceed along the Down Through line. He said that he did not touch lever No. 157, knowing that the road over 

crossover No. 260 would be set for the passenger train and that he would not be able to draw it.The light indications in the 

frame were then as follows :-

Above lever No. 197 double yellow.

Above lever No. 141 green.

Above lever No. 156,yellow. 

Above lever No. 157 red.

Beach stated he did not tell Kenward about the light engine and there was no discussion with Inspector Jones about it ; there 

was no necessity to speak to either as lever No. 157 which would control its movement, was in his section of the frame. He 

followed the passage of the engine on the diagram, replacing signals Nos. 197, 141 and 156 after they had been passed and then 

Inspector Jones drew his attention to the fact that track circuit No. 98 had become clear. At that time the indication above signal 

157 was Red; he took particular note of this fact. Signal No. 159 on the adjacent Down Local line was also showing Red and all 

levers affecting that line were normal.

On being questioned, Reach said that had signal No. 157 been cleared before levers Nos. 260and 261 had been reversed, then it 

would have changed to Green, as the section ahead was clear and the next signal (an automatic) would he at Green. In that case 

signals Nos. 156 and 197 would also have shown Green aspects He stated that at the time of the accident there was a lineman in 

the box but he had not been given any possession and had not removed the covers from any of the locking.

7. Leading Motorman H. H. Atkins of the Tattenham train knew the road thoroughly. having been 10 years at Tattenham Corner. 

He had, he said, a clear run up to the last automatic signal, which was at Yellow. Signal No. 261 was at Red but turned to 

Yellow when his train was about two coach lengths away ; he passed it at a speed which he estimated at 15 to 20 m.p.h. He 

observed the set of points No 260 and as he was taking the turn-out he looked up to see the aspect of the next signal, No. 259, 

and saw it turn from Red to Yellow. At the same moment he saw the light engine approaching on the Down Through with no 

controlling signal between it and his train. He applied the brake fully and released the dead man's handle, but he did not have 

time to whistle. The train came to a stand on the diamond crossing but the light engine struck the centre OF the cab at a speed 

which he estimated to he 10 to 15 m.p.h.

8. Guard W. Temple, who also knew the route well, said that the passenger train had a clear run and was on time. The rear brake 

compartment which he occupied was fitted with a periscope, and he was using it. He stated that he saw the signal No. 261 

change from Red to Yellow ; he added that it is difficult to

judge distances through the periscope, but he estimated that the train was five yards away from the signal when the aspect 

changed. As the leading coach was taking the turnout he noticed the chimney of a light engine on the adjacent Down track he 

endeavoured to make an emergency brake application but the motorman had already acted. The collision occurred almost 

immediately afterwards.

9. Driver R. Hilson, in charge of the light engine, was entirely familiar with the route, having worked over it for the past 10 

years. The engine arrived at No. 10 Low Level platform at about 10.33 a.m. having travelled via North Kent (East) Junction ; 

after waiting a few minutes, Hilson telephoned to advise the signalman that the engine was to go light to New Cross Gate. He 

said that he was not certain exactly what the signalman replied but he took it to he somewhat sarcastic and uncivil and he told 

Fireman King about it. Almost immediately Hilson observed that the Platform Starting signal No. 197 was at Double Yellow for 

the Down Through line ; he mentioned this fact also to King and then started the engine.

Hilson went on to say that the next running signal (No. 156) showed a single yellow aspect ; he stated that before passing it he 

shut off steam expecting to h d the next signal (No. 157) at Red, but he opened the regulator again when he saw that it also was 

at Yellow. He again shut the regulator before reaching signal No. 157, which he said he passed at about 15 to 20 m.p.h. ; almost 

immediately he saw an electric train come on to the crossover directly in the path of his engine. He made a full brake 

application but before it could take effect the engine struck the front of the train.

Hilson stated that he did not see signal No. 156 at the same time as No. 197 ; also tbat he did not observe No. 157 until after he 

had passed No. 156. He was sure that he did not see signal No. 157 change from Red to Yellow and asserted that at no time did 

he see signal No. 157 at Red. He said that he could not see the aspect of the first automatic signal beyond No. 157 on account of 

the sun hut that this did not affect his vision of the controlled signals.

Hilson was certain that apart from the remarks mentioned above, there was no conversation on the footplate. He did not notice 

the aspect of signals on the adjacent Down Local line, though he agreed that he had probably done so subconsciously. He 

related that, having seen the aspect of signal No. 157, he looked out " unconcernedly" through the spectacle glass and saw the 

electric train some distance ahead on the Up Through line ; a little later he looked out of the side of the cab and saw the train 

take the turnout in his path. He had not obsemed the head code on the train and said that had he done so he would not have 

recognised it nor would he have known that the train would be crossing over to No. 1 Up line.

Hilson was questioned closely hut was adamant that he never saw signal No. 157 at Red nor any signal at Green ; he remarked 

that the former was a "good clear yellow" which he could not possibly mistake. When asked his reactions if told that it was 

impossible for signal No. 157 to be at Yellow he said he would never believe such a statement.

Fireman King had not recovered sufficiently to attend my Inquiry ; he had, however, previously stated that he had been firing 

and attending to the injector and that he had observed no signals and could give no useful information.

10. Lineman G. P . Hurst was in the signalbox at the time of the collision, endeavouring, unsuccessfully, to obtain possession to 

work on points on the Down Lines. As soon as he heard of thecollision he examined carefuuy the position of levers in the frame 

and found Nos. 156 and 157 normal with red indications Nos. 260 and 261 reversed, the latter with a red indication, and No. 

259 reversed with the indication at Yellow. He then went to the site of the accident, 0 h s e ~ i n gen route that signals Nos. 156 

and 157 were at Red and were giving good indications. He recalled that both the driver and the motorman, when questioned by 

him, replied that signals Nos. 157 and 261 respectively were at Yellow, but as they had been injured he did not press the matter 

with them.

Hurst then returned to the box and made a cable,test and also tested the electrical controls on the levers concerned ; he stated 

that the result of both was satisfactory. Later, after the re-railment, he tested the mechanical locking of the frame and found that 

also in order. He stated that signal No. 157had given no trouble and that during the 17 years he had been responsible for the 

signalling installation at London Bridge there had been no danger side failures.

11. Mr. F. Evans, Signal and Telegraph Inspector, London East Area, happened to be at London Bridge when the accident 

occurred. He went straight to the signal box and saw that the position of the levers and the aspects of visuals were as described 

by Lineman Hurst. He then proceeded to the site of the accident and he also saw that signal No. 157 was giving a good red light 

; he said too that it was correctly focused. He returned to the box and was present when the electrical tests were undertaken and 

confirmed that the results of these were satisfactory. He stated that it was not possible for the light indicators in the frame to 

show an aspect different to that of the signal to which they referred, nor for signal No. 157 to show anything but a red aspect 

with levers Nos. 260 and 261 drawn unless the connections were deliberately transposed ; he added that this would become 

immediately evident to the signalman and also when tests were made.

Continuing, Mr. Evans stated that there had been no failure of signal No. 157 for as long as he could remember. The wiring of 

the signal circuit had not been disconnected for the past 18 months, but the periodical cable tests had been made, the last one 

being on the 16th March, 1949. The mechanical locking of the frame had also been tested at about the same time. During the 

last 20 years, for 16 of which he had heen in charge at London Bridge, he had not known of any danger side failure.

12. The interlocking and electrical control or the signals and points concerned in this accident are quite straight-forward and 

there is reliable evidence that they were fully tested after the accident and found to be in good working order. The road was set 

for the Tattenham train and levers Nos. 260 and 261 were drawn ; in these circumstances lever No. 157 could not have been 

reversed and the aspect of the signal must have been Red. The accident was therefore clearly caused by the light engine passing 

signal No. 157 at Danger.

13. Driver Hilson, was, however, very certain that signal No. 157 was at Yellow and Lineman Hurst related that the driver 

mentioned this to him a few minutes after the accident in which he (Hilson) bad been injured. It is necessary, therefore, to 

consider whether the aspect of that signal might have been other than Red at any time during the approach of the light engine. 

Such a circumstance could have arisen only if, in addition to levers Nos. 197, 141and 156,Signalman Reach had drawn lever 

No. 157for the light engine before Signalman Kenward bad reversed lever No. 260 for the Tattenham train. However, had Reach 

pulled lever No. 157, thinking that the light engine could have, cleared the crossover without checking the incoming train, or 

had he reversed the lever accidentally before Kenward had started to make the lever movements for the train, then signal No. 

157 and also signals Nos. 156 and 197 would all have assumed a green aspect, the automatic signal ahead being at Green. 

Driver Hilson was as definite that none of these signals were at Green as he was that signal No. 157 was at Yellow. Again, had 

lever No. 157 been drawn it could not have Been replaced to normal after the engine bad occupied approach track circuit 97A 

and 98, and then the cross-over could not have been reversed nor signal No. 261 cleared for the passenger train.

Hilson was very certain that he did not see at any time signal No. 157 at Red and that he did not observe it change from Red to 

Yellow. Yet he agreed that when he saw signal No. 156 at Yellow signal No. 157 must have been at Red. I observed, when 

viewing the site, that signals Nos. 156 and 157 could both be seen clearly from a point on the Down line opposite the box and it 

is difficult to appreciate that a driver could see one without noticing the aspect of the other.

The possibility of Hilson having mistaken signal No. 159 on the adjacent Down Local line for his signal does not arise. Hilson 

stated that he had not done so and the levers relating to that line also must have been in their normal position before the road 

could be set up for the Tattenham train.

14. I am, therefore, in no doubt that signal No. 157 was at no time during the approach of the light engine showing an aspect 

other than Red, and I have no alternative but to place full responsibility for the accident on Driver Hilson for having passed that 

signal at Danger. Thc nature of his evidence suggested that he was not concentrating his attention on signals and it also seems 

possible that he was feeling some resentment against the signalman whom he considered, without any apparent jutification, had 

been rude over the telephone ; although denied by Hilson, I would not be surprised if he and the Fireman King were discussing 

the matter. I can only conclude that Hilson completely missed signal No. 157 and that the signal which he was so certain was at 

Yellow was, in fact, the previous signal, No. 156.

Hilson is an experienced driver with 31 years service with the Railway, during the last 14 of which he has been driving, and he 

has a good record. His sight is good and there is no question of any colour blindness.

15. No blame is attached to Leading Motorman Atkins, who Is to be commended on his alertness in stopping the passenger train 

in so short a distance as 40 yards.

16. The over-run beyond Signal No. 157 is only 103 yards but this is not in any way considered to be a contributory cause to the 

accident, for the driver of the light engine did not apply the brake until he had passed the signal and saw the electric train take 

the crossover in front of him.

17. I have no recommendation to make regarding this accident which was brought about by an inex- cusable lack of 

concentration on the part of the driver of the light engine who failed to observe and obey a well-sited colour light signal at Red.
