Putney Bridge station has a main line shunt move, to reverse trains West to East. This is similar to the main line reversing shunt moves at South Ken, Embankment, Hornchurch etc.
However Putney Bridge does not have a wrong road starter on the EB platform. Does anyone know why this is the case? It seems pretty odd

I've got a note somewhere - it might be to do with the fact that when the signalling was planned around the service all the levers in the IMR were already used and didn't warrant another 12 lever section. I might be utterly wrong here, but there is a sound historical reason for it.

Isn't it to do with the Network Rail boundary?

That's why the IMR is full.
Edit: or was as full as the NR side would permit....

I'm going to go with there not being enough levers!
Though you only have to go to Parsons Green to do an East to West, albeit via a siding!
It is also the same at Hatton Cross and Hounslow Central.

Is regular reversing still carried out there? I know in the 60s-70s a common off-peak practice on the Wimbledon branch was to reverse "Wimblewares" at Putney Bridge, with only ex-Wimbledon trains serving the "main" District metals east of Earls Court.

There is one C stock late at night that reverses in the bay (departing empty to stable at Parsons Green) and one D stock, also late night, that reverses on the bridge (having run empty from High St Ken).

My guess is because it (and likely the other set mentioned by ADW) stables on 27 upper/lower. I'm assuming 21...24 are full at that time and thus couldn't be used for a WB-EB move, so the turn is made at the bridge, entering 27 off the EB. On the other hand, I may be incorrectly applying some form of logic  /Jimi |

The D stock does indeed stable on 27 road, the C stock stables on 29 road.
In fact both the 27 road stablers should stable before any of roads 21-24 are occupied, and the second one does go via 24 road.
I think the reason for the first of the 27 road stablers going via Putney Bridge is simply to do a "rusty rail" move and keep the points working. Sometimes the move doesn't actually happen, the train being reversed in one of 21-24 roads instead, particularly if it runs late.

Thanks. As a mere passenger, I'm not entirely sure where all those stabling roads are - I take it 21-24 are between Parsons Green and Putney Bridge and 27 and 29 on the "town" side of Parsons Green station.
Still doesn't explain why the train runs empty stock, though.

Yes, 21-24 are between Parsons Green and Putney Bridge. 27 is the other side - between Parsons Green and Fulham Broadway. 29 runs down the back of the westbound platform. Still doesn't explain why the train runs empty stock, though. The trains are emptied in bay roads so that any delay in detraining (such as passengers asleep) will not hold up other trains. |

My thanks also ADW! I recently had a related discussion with Chrish concerning moves in and out of PAG sidings. He accused me (correctly) of trying to apply too much logic ;D when I was trying to fathom the early morning exit moves from 27 road (via 24 road!). I find the 'how and why' of the operational side of the railway fascinating. Your explanations have given me yet more insight into this location, which we'll use to create more realistic scenarios for our 'virtual District' on MSTS. Thanks again!
Best regards, Jimi

Trains have reversed E-to-W from the Putney Bridge EB platform during planned engineering work in the 1990s. The points were "blown over" by an AET, No.8 crossover secured reversed by a DTM and a green flag hand signal shown to the T/Op (by then PG Train Crew Manager Martin O'Reegan!). I wonder if this would be possible in today's risk-averse, nanny state, LU?

It is also the same at Hatton Cross and Hounslow Central. Hatton X and Hounslow Central both have (colour light) wrong road starters for reversing W to E. |

On the desk next to me (ready for when I can get to a photocopier) I've got a fascinating paper from the Institution of Railway Signal Engineers that details the introduction of Programme Machines on the Putney line; it covers the workings at Putney Bridge and Parsons Green in a very high level of detail - explaining that this was set up to allow 'Depot Working' with PMs, the wiring diagram for the siding allocation panel, train count and scanning circuits is a work of art in itself!

The Parson's Green PM set up must have been quite clever in its day. The shunt panel was still in the old train crew managers office a few years back. |

Oh, very much so - the photograph of the supervisory panel at ECt is interesting as it has the same style of TD set up switches that are on the shunt panel - think the photo dates from when this was pretty much the only bit of equipment in ECt - right at the start of PM working.
