I'm currently on a westbound train to Uxbridge that has stopped at Ravenscourt Park, Stamford Brook and Turnham Green. It's on the fast line and a District train has been running alongside so no problems on that line. The train op was making regular announcements about the stopping pattern but no explanation was given. Service intervals seem OK at the moment. Anyone got any idea why this would happen? I've known the odd unscheduled stop occasionally but can't recall an all stations during normal service before.

Maybe the District train was going to Richmond and you were filling in a gap in the Ealing service?

The District line was advertising severe delays earlier so perhaps the District train running alongside this particular Picc train was just coincidence. I imagine the Piccadilly trains either all stop or none stop.

Thanks for the replies and simple explanation. I didn't realise there were problems on the District. I must have got lucky when I used it a little earlier, 2 trains, no waiting for either and both quiet.

Not sure if the right place--but a thought about the normally non-stop platforms between HS and Acton.Picc:trains go at full speed through these platforms which have punters walking about on the District side who often wander over to the fast platforms.How does this square with the rule about slowing down through stations? I know Wembley park has full speed through the down fast but in that case there is normally no access to that platform

I know Wembley park has full speed through the down fast but in that case there is normally no access to that platform Slow speed through platforms is more to do with signalling than anything else. Historically there have always been platforms listed as having a higher permissible speed for non-stopping trains, especially on the District Met and Picc lines. The fastest I've ever been through a platform probably was on the Central however, one weekend 15-20 years ago when trains were running non-stop from Hainault to Woodford during engineering work. Passed through Chigwell at the full 100 kph in coded manual.

Yes, although if we are running non-stop down the local line, we have a 20mph speed limit through those stations. Incidentally, whilst on the fast lines, if any station starter is at danger, we tend to stop just before the beginning of the platform. Stopping in the platform and not opening doors will cause other issues!

There are shorter overlaps on the local line to allow for a higher frequency service as trains stop and start away from stations. The fast lines have longer overlaps to reflect that trains won't stop. Incidentally this is the biggest issue on trains stopping at Turnham Green all day, as they would slow down the service as trains take longer to clear each section.

Incidentally this is the biggest issue on trains stopping at Turnham Green all day, as they would slow down the service as trains take longer to clear each section. Thinking about it, another factor also is that for trains to run through a platform at speed, the station starting signal may need a repeater. On a line like the Northern few if any platforms had this (struggling to think of a single one from memory). Otherwise the driver needs to assume the starter is at danger, which in practice means the train is likely to need to almost stop at many locations. It will be noted that on lines like the Rayners Lane branch there is an additional repeater signal in the rear of the platform at many locations, repeating the aspect of the starting signal.

It's a bit like Plumstead on the Southeastern line - The platforms are dead straight, and the signalling designed to allow a fast train to run at around forty miles per hour through the station on a fast service.

Currently running down the locals due to track circuit failure at Ravenscourt Park EB Fast
