Was on the Central this afternoon between NHG - CHL and return, and despite the trains I was on were getting really lousy codes (congestion and slower speeds) the station approaches didn't seem anywhere near as quick as they usually do. Even coming in at a relatively low speed, the train was coasting/on a light brake for a lot longer than normal, and also trains were braking a lot earlier than usual. Has the ATO been altered slightly, or was it just me  |

You probably had trains in front that had just departed, and the ATP was holding the codes down to enforce a safe overlap on the station approaches. The signalling on the Central can actually handle quite tight run-in/run-out at the Zone 1 stations.

I've said it before on the forums and to you, Alex, but you can actually see the train behind you pulling into the platform in the in-cab monitors as you pull out...

The Central's signalling supports approx 60sec roll out roll in times in the central area, which is good, but not impressive. (It's roughly equal to having 3 multiple home signals). The speed at which the train runs into the station behind the other depends on how close it is to the train in front, the spacing of the signal blocks, and the speed limits for that area.
In the case that Alex observed, maybe the train was being driven in CM?

All lines are due to get a new WTT in May for Ken's late running at weekends.

With the target speeds, which bits of line could you get a target of 100 kph? I know between North and East Acton it can go up that high.

All the trains are currently restricted to 85kph post Chancery Lane.
Even if they weren't, I'd be surprised if you could reach 100 on that stretch. It used to be quite common between West Ruislip and Ruislip Gardens though.

So that's about 52.8 mph. Is it fair to assume that between WER and EAA that you could get a 100 kph target along the whole thing? My list of speed restrictions dating from 1993 says this is possible.
