Sorry if this is in the Wrong Place. cjolly.mysnaps.org.uk/p30428136.htmlIn this photo It makes mention of a Call-on light( the orange light in the offside window) What exactly does this light mean? Is it only on A-stock? (BTW: Great pic Christopher J) |

C stock and D stock also have them and AFAIK all the tube stocks too.
When the driver of the train behind has been told to draw up behind (usually for a pushout of defective train) the driver of the train in front will go to the rear cab and light the call-on light to tell the other driver it is safe to approach.

Erm, he doesn't always have to go to the rear cab (not sure about 'D' here though), he can switch it on from the leading cab and remain there. The whole point is that staff can then safely board without the need to speak to anyone or have anyone come to them.
The idea of the calling on light is to give assurance to assisting staff that the train they are about to board is secure and will not pull away while they are clambouring onboard! So, you have a defective train:
The driver of the def stock needs assistance from the rear and switches on his calling on light.
To switch it on he has to remove his selector/reversor/RKL220 key, which prevents the train from being moved.
The driver of the train behind or other staff then see that the light has illuminated at the rear (it comes on at both ends) and knows it is safe to approach and board.
Staff then board the train at the rear and use the through Comm's to come to a complete understanding with the driver (who is at the front).

To use the auto-coupler, does the driver of the assisting train draw up to the stalled train and then press the 'couple' button, or are the trains not coupled?

If only it was that simple! ;D If a train requires a push out, there are an awful lot of things which need to be taken into account first. On the District, we can have a D stock coupled to a C (or vice versa) and as the two aren't compatible, extra precautions are needed including presspahn shields over the studs on the couplers etc. On the C&D stocks, the couplers aren't simply 'push buttons'! They have cocks which need to be set in both cabs before then after coupling... The procedure is a lot more complex than you'd think, but I can't be bothered to list it all here... I'm leaving in a few weeks so I can start to forget all this stuff! ;D ;D |

On an A stock, when the parking brake is applied, the call on light illuminates. On other stock it is a specific switch for it, but as i say on the A stock, the call on light is switched on my applying the parking brake, which makes sense!

AFAIK the calling on light on an 'A' was an addition when OPO came in. The other surface stock had them from day one, so it was more integral rather than an add on as on 'A'. On 'C' and 'D' you have to put your key in it which means you are then prevented from driving, on 'A' it means the parking brake is on which again prevents you from driving. Different methods, but the same effect!

Reminds me of the 455s on the southern region. You could aparently go around all day in step one and never even notice!
I'd think that the effect would not be the same with the parking brake though...

Very early on in my driving days I accidently dragged a 'C' Stock with the hand brake on from Hammersmith to Goldhawk Road. I was desperately trying to figure out why I had such sluggish movement, and then on arrival at Goldhawk I noticed the heat haze coming from the Hand Brake. Woops!
The Area Manager met me at Baker Street and with a very stern look asked if I had taken a chisel to the wheels. Before I had a chance to reply he ordered me empty back to Hammersmith depot! He never took any disciplinary action because he knew I would never do that again (and I didn't!).
