Fully understand you weren't criticising. I'd like you to fully understand that I wasn't criticising either. My point about the close to 40 min wait was simply to give others an indication of the time-scale, not to criticise the crew who helped the customers out.  |

Thanks for the response prjb; I know I can be negative about the S stock, but thats my own problem. I hope however that tonights testing and simulation allows a good resolution to your current own If you have ever been negative Ben I have never come across such a post. You always seem quite positive to me and generally just want to understand more about the topic in hand. |

And don't let people like that nasty deadmans get you down  ;D ;D ;D |

Is there any reason why the train could not have been pushed out. Can an A stock push an S stock or the other way round or would they need an adapter to couple?

The A and S stock both have wedgelock autocouplers. The S stock has air-only couplers on the cab ends. I assume they are at the same height, would be bloody stupid if they weren't. So they are likely able to push an A stock along, or be pushed by an A stock. |

Yes they can. I remember reading a message a short while after the first S stock was delivered to Neasden about them doing a test to prove that it was possible in practice (it was always possible by theory and design). iirc it went mostly to plan, but they initially had a bit of a task to get them apart again afterwards, but whether this was a single-time issue or one that is likely to reoccur I have no idea.

I'm sure the S Stock will make it. After the agonies that the 73TS went through for years, it became one of the most reliable stocks on the system. Mind you, a lot of money was spent getting it right. As for the S Stock door opening trouble, I found getting it to stop in the right place was difficult, and I was on the simulator! I thought it was just the simulator. If it's not and the real thing is also difficult to stop in the right place, the simulator was very good! My impression was that the sighting is difficult but this will improve with practice. The other point is that, if the CSDE system is designed for future ATO, it will be set up for +/- 250mm. This will cause trains to lose time while drivers position the cab in the right place, like the Jubilee PED situation. Perhaps the range needs widening. Oh yes, did anyone do gapping tests before letting the trains go into service? The CSDE is set up for nominally +/-1m, worst case of 0.75m. This is more generous than, say Central or Jubilee in manual driving. Most find it easier with a real train than the simulator but it does take a bit of practice. Yes, gapping analysis and testing was undertaken. There were two faults on the incident train. Since then more testing has resulted in additional briefing on handling trains not performing normally and further technical enhancements to follow. |
