 On my way home today, I saw a 73T/S (in motion, in service) with its headlights illuminated at both ends. I'm sure that the rear cab couldn't have been opened-up, as I know that you lose pilot light if both cabs are on. So... what could have caused it?

This train had an electrical fault as headlights shouldn't normally be able to be on at both ends simultaniously. |

Hmmm....
Sounds like those guys in Northfields Depot need to take a serious peek at that '73', Seth.
Good to see that your avatar is free from that particular defect though.... Red lights!! ;D

Sure it wasn't the mini headlights that come on when the "M" door detraining steps are deployed?

This sounds to me rather like the driver was in a hurry to change ends and the barrel of the control key switch was not fully turned and the contacts were still making. If the key or barrel are worn it is possible to get the key out when it is not fully open. This used to happen sometimes when a Guards position switch key barrel was operated too quickly. As the contacts on the barrel are staggered some will be open and some still making albeit only slightly.

I am not so sure that you would loose your pilot light, but you do run the risk of blowing a coupld of fuses, as the train is 'open' at both ends. You do of course get a warning on the CDU that 'other cab on'! |

When I was testing the RPAs & line brakers on a unit, I forgot to take my key out and the ATM who was trying to take the train on juice couldn't get pilot light as a result. Thankfully we didn't blow any fuses, nor did we trip any MCBs. |

Thankfully we didn't blow any fuses, nor did we trip any MCBs. I wasnt aware of that, as even the stock course for the 73ts (who is delivered by a very senior I/op) didnt say that. I know if you have a cab door open at the opposite end of your train to the cab that is on, you will loose your pilot light, as they becaome part of your train door circuit. But surely they shouldnt have moved the train or even put their key in with the 'other cab on' illuminated on the CDU, as there can be quite significant affects? Nope, definitely the headlights. IIRC the switch that operates the detraining light requires an RKL key to operate it anyway. Correct. This is so that you would have to shut down the desk you are using to put your RKL key into the switch. This stops you from having the detrainment lights on whilst on the move. |

Ultimately it was my fault as I forgot to take my key out. Something else occurred to me though, albeit slightly irrelevant. Wouldn't the key need to be in at both ends to enable use of the Cab to Cab radio? |
