I'm not sure if this should go here, in historical or even signalling, so if it gets moved one of the other admins has different ideas ;D
When I were a lad, for some years at least ISTR the Olympia shuttles used to reverse at Earl's Court regularly as per WTT. How did this used to happen? In my own mind I'm sure they used to reverse off Platform 1, but that is only a memory - in addition I've looked at Harsig's excellent 1957 signalling diagram and am not sure that move was possible (it certainly isn't signalled now).
If it wasn't done that way, does anyone know how it WAS done?

I can only remember the Olympia service being Exhibitions only, and that they reversed at High Street Ken, or possibly Edgware Road if they were six-cars. It was either CO/CP or R Stock.

From when I first remember traveling to Olympia in the fairly early 50s they arrived at an eastbound Earls Court platform empty, and I'm sure they had Olympia in the windows. I think the designation when they arrived back from Olympia was High Street Ken.

There's one trip in the current WTT (Sundays late night I think) where an Olympia trip reverses at Earls Court by running to EC No 2 platform, detraining, drawing ahead, and using the crossover east of EC to reverse into EC WB No 3 platform. Its the last Olympia trip, so tha train then heads back to Ealing Depot I think. |

Also ocassionally if one Olympia train is diverted elsewhere sometimes the remaining one does Olympia - Earls shuttles as described to maintain a better service. Also popular when a problem prevents access to High Street, one Olympia train goes to Parsons Green (usually, though Mansion House, Whitechapel and Plaistow are all known to get one out of the way for a bit!) and the other train shuttles as described. |

What is being thought of is the days when the Olympia service was an 'Exhibition only' service, and was run accordingly.
It was then Olympia <-> Earls Court only. Ex Olympia the train would arrive at Platform 2 at ECT. It would detrian, the train would draw forward to a limit of shunt mark, the driver would change ends (though I suspect that in the days of crew operation the gurad would have done this bit!) and when signals allowed, would cross over to P.3.
This move is regularly used today - indeed it is still timetabled early mornings for a number of trains - albeit they then go as timetabled; I don't recall that Olympia trains are timetabled for this, except under some specail working Time Tables.
Later this service was extended to High Street - it does cause congestion at ECT - but still only 'Exhibitions only'. Permament Olympia services followed later.

Hi Dave! What is being thought of is the days when the Olympia service was an 'Exhibition only' service, and was run accordingly. It was then Olympia <-> Earls Court only. Ex Olympia the train would arrive at Platform 2 at ECT. It would detrain, the train would draw forward to a limit of shunt mark, the driver would change ends (though I suspect that in the days of crew operation the gurad would have done this bit!) and when signals allowed, would cross over to P.3. Do you recall whether or not this ever caused blocking back into platform 2? Presumably the service would have run through peak hours during exhibition days and thus would have had to thread in and out of the ex-Wimbledon trains. This move is regularly used today - indeed it is still timetabled early mornings for a number of trains - albeit they then go as timetabled; I don't recall that Olympia trains are timetabled for this, except under some special working Time Tables. Later this service was extended to High Street - it does cause congestion at ECT - but still only 'Exhibitions only'. Permanent Olympia services followed later. Did the exhibition-only services continue to use Platform 3 at HSK? |

You firstly need to remember that I wasn't working for London Underground at the time and it is my recollection of memory and things I recall reading that I'm dragging up here...... I'm sure that others who visit here will be able to correct or confirm my thoughts!
I *think* this may date back to the 'old' signalling arrangements at ECT when it was possible to route trains ex-Wimbledon into P.1 (ie before the crossover was removed to P.1). As to the hours of operation I'm afraid I cannot enlighten on this, but I recall that the service would have been operational during at least the evening peak.
A degree of congestion by using the shunt from P.2 is almost innevitable, though remember that trains from P.2 can be routed via signal EC7 (the one which divides the route normally associated from P.1 to either HSK or Gloucester Road and the route taken by the Edgware Road service) so, given that traffic density was not quite that of today, it probably wouldn't have impacted as much then as it would now.
I've no idea which was the 'normal' platform at HSK when the Oly's started going that far!
Perhaps others can enlighten more?
