Hi guys, Sorry if this has been mentioned already in a Signalling thread but while waiting at Seven Sisters platform 5 today, a train came down from Northumberland Park Depot in ATO. The driver was standing up and had the J door open and was talking to another member of staff, no hands were on the controls. So has the depot line been made ATO? The train was 100% from the depot because it had just been through the train wash and smelt heavily of cleaning solution. If I wasn't seeing things, then when was in made ATO? Because I was here in July last year when the DTG Signalling was installed and can clearly remember that they were being driven manually when they came out the Depot access road. Anyone?  |

I'm sure seaeagle will be able to provide an answer, but in the meantime, perhaps a rough time would help to see if it were a staff train or a daytime stabler.

From memory it's all manually driven within depot confines up to the last outlet signal (VNP 1937?) and when that clears it's all ATO. AS SE13 says, Seaeagle will be able to confirm.

That is exactly what happens, a train coming from the depot has been manually driven to the outlet signal, then auto from there. A train reversing at Seven Sisters sidings, is driven manually into the siding and comes out in atuo. |

seaeagle when was this commissioned may i ask? (the trains entering platform 5 in auto from the outlet signal). Because the new signalling was in at seven sisters last July yet the trains were still coming in manually?

Would have been towards the tail end of last year, October/November time, can't remember exactly off the top of my head. |

When I was on the Victoria Line in the 70's,some of the lazier ATO's used to put train in auto after passing the outlet signal and rely on the pressure switch brake to stay below 22mph.I believe one guy got caught out when one of the signals approaching Seven Sisters didn't clear and he overran it.

Did ATO used to be a rank for train operators?

Did ATO used to be a rank for train operators? Yes it did- ATOs on the Vic and the Hainault - Woodford shuttle on the central were paid a higher rate than drivers on other lines until the company plan standardised pay rates |

Presumably it stood for Automatic Train Operator?

At least 60% of the ATOs would put the train into auto and let it go but most remembered that there were no brake commands on the appraoch to Seven Sisters and at least 6 that I knew over ran. |

Would have been towards the tail end of last year, October/November time, can't remember exactly off the top of my head. Think bi-di was commissioned last July (had to look it up, time flies Rail Engineer Link). Seems about right as the commissioning was last things I did before changing jobs. Edit - may have been some ATO data issues that were not corrected before the Olympics, so would think it auto was allowed sometime just after the Olympics. |

Can someone explain what the Pressure Switch Brake is?

It was used in two ways,first to hold the train in the station when it had come to rest secondly it was used in speed control when close behind a preceding train.If speed dropped below 19mph motoring came on if speed got to 22mph the pressure switch brake came on.The max pressure of this brake was only 14lbs per sq in.
