Hello folks,
Yesterday when we came through the W&C, I noticed that when we got to Bank the driver locked up, jumped out of his cab & headed towards the other end. I glanced back and saw that the train still had white lights on the front, why is this? I would have thought that if no-one's there to drive it when they lock up the front should switch to red (rear is already red, obv). OTOH, I know that on this particular line it can't go forward because there's buffers in the way, so it's not as if the train will get biffed by another train coming in the wrong direction, but this stock isn't restricted to this line, is it?
Cheers,
AI

Well Irish practice with DMU's and EMU's is that the marker lights / tail lights will only change between cabs when the driver cuts in the 2nd cab. So applying that to the scene you saw.
Train arrives into Bank and driver cuts out the cab, Marker lights . tail lights remain as is. Driver walks to the other end of the train and cuts in, that is when the marker and tail lights will change.

Not sure about other lines but the A60/62 stock seems to be a little different. I've seen trains coming into Baker Street roads 1&4 with tail lights on, and the t/op cuts the headlights halfway along the platform. I've also seen A stock going along with the headlights still on at the trailing end!! They are old trains though.

Funny you should bring this up www.flickr.com/photos/24772733@N05/3044089678/I took this view whilst working at Waterloo station. The train is on the normal No.5 reversing road which has been altered to avoid going right up to a brick wall (which is what allowed me to 'get behind' the subject). Point is the T/Op had already changed ends when I took this view from the official walkway so I was in no danger of being run over, even though it looks that way with the headlights still on in an inactive cab. |

A stock is now unique in that the head and tail lights are operated independently by their own buttons, rather than by the control switch (or equivalent) as on the other stocks. So it's possible to forget to switch the headlights off/tail lights on and vice versa. I think irishunderground is correct in his description of how they work on the 1992TS. |

92ts - used on both the Waterloo & City and Central lines - does indeed operate as Irishunderground says.
I was often confused by seeing the same thing happen at Ealing Broadway - but the way it works was described to me by our very own Solidbond and a member of LU's rolling stock department whilst at the S stock meet last year.
On 92ts, the white lights will remain on at the end where the cab was last active, and will only change to red when another cab is opened up.
On the stocks where you see the usual white lights along with a single red..........the single red light is the stabling light. Depending on where you see it, the driver will have either turned it on too early or they've forgotten to turn it off.

On the main line a driver forgetting to change over the head/tail lights was usually greeted by an oncoming driver putting his head near the windscreen and patting his head...headcode you see! whereas a driver seen patting his head on the front of a train at Waterloo, having been given the "right away" by the guard meant "no air", unable to release brakes.
