S7 Stock SDO beyond Earl's Court

Does that mean Gunnersbury is also out as an easily usable potential reversing location? I know it was never a regular move, but would be good to know?

Currently:
Ealing Common both
Acton Town EB
West Kensington EB

West Ken 2 EB - 2 rear doorways
Gunnersbury 1 WB - 1 front doorway
Acton Town 4 EB - 1 rear doorway
Ealing Common 1 WB - 2 front doorways (may be reduced to 1 doorway after platform rework)
Ealing Common 2 EB - 2 rear doorways
Ealing Broadway platform 7 - 1 doorway furthest from the buffers
There are also multiple S7 door cut outs for the rare use of platforms 2 & 3 at Acton Town and Hammersmith - the regular Piccadilly line platforms.

And yes, there is a signalled west to east reverse facility at Gunnersbury.

It's kinda interesting how there is no SDO at westbound platform 1.

Oh yeah sorry, I didn't read it properly.

Presunmably these are all temporary based on platform furnature, as the platforms are physically long enoung?

Yes, Ealing Common is constrained by the bridge hole at one end and the turnouts to Ealing Common depot at the other end. West Ken EB similarly by the bridge hole at one end and the turnout to Lillie Bridge depot at the other end. Re-configuring the west end crossover doesn't help this.
However on both these on the EB there may be scope to move the stopping position about one doorway east if and when ATC signalling is done and we don't need to sight visible signals from the cab. So it might reduce to one door cut out.
Places like these almost certainly must have had to cut doors out back when 8 car R stock trains ran I guess?
It was probably a lot easier as the platforms weren't populated with OPO monitors and the signal sighting rules probably weren't as now. Perhaps that last wasn't a good thing!

Is Acton Town WB also subject to SDO? I noticed a sign tape up facing drivers that said the doors of the front car would not open. Unless I am mistaking something?

I'm fairly sure that's a reminder to T/Ops to tell the passengers it's currently two doorways cut out at Ealing Common WB, not the one that the CIS (DVA etc) tells you about, programmed ready for when the platform is finished....,

No, the motorman stopped on the 8 car mark, simples. If he had a 6-car, he stopped on the 6 car mark. some places the front doors would have to be cut out by the motorman.

Ermm, maybe not as a steam loco's cab was about 40' from the front of the loco! If the front of the loco went past the signal which may be displaying a red aspect then it was treated as what we now call a SPAD.

I was talking to a District line driver earlier and he said that there is 1 or 2 s7 formed services on the Richmond/Ealing Broadway a day and I might want to catch it if I can from Ravenscourt Park so could somebody please give me the exact timings when it gets into Ravenscourt Park.

Thanks
