Wembley Park - old Platform 6

Of course it is still there and clearly shown on the Google Maps satellite image, note the overbridges and particularly the ticket hall overbridge with four clear staircases down to the single platforms 1 and 6 and the two island platforms 2/3 and 4/5.

Railtech, You misunderstand me. I (and J Graeme Bruce) said south of the exisiting station - in reality looking at Google maps - more like to the ESE. Even forgiving a senior moment, I understand that the current Platform 6 is still there and visible on Google maps!!

Metman, Many thanks. I don't think it was a terminal platform by the look of it but I could be mistaken so I am somewhat confussed, please see below.

For the purposes of scholarly study, the following extract from "Steam to Silver" is reproduced below so as to remove any possible ambiguity as to my original enquiry ...

The book doesn't say unfortunately.

The train is, as you suspect, heading south towards Neasden to the right of the image. I suspect that the reason the two exhibition' platforms were built south of the road bridge was simply to avoid the expense of widening the road bridge to accommodate extra tracks.

The 'exhibition' platforms (Nos. 5 & 6) were provided in 1923 and were terminal platforms accessible only from the south. They had their own separate entrance building on the opposite side of the road with no direct connection to the rest of the station.
Subsequently, in connection with the construction of the Stanmore branch a new through platform (No 5) was provided as part of the main station and this entailed the removal of the exhibition station platform 5, leaving just the platform shown in the photo above.

The arrangements after the opening of the Stanmore line are as shown in this diagram

You'll have to zoom in to see the detail.

The photo above is almost certainly this one on the LT Museum Website and is thus dated 1933.

This platform succumbed as part of the general reorganisation of tracks between Finchley Road and Wembley in preparation for the extension of Bakerloo Line services to Stanmore. A new platform 6 was provided as part of the existing station, but interestingly it was still only usable by passenger trains from the south (or entering service from Wembley Park Sheds) until further track alterations in 1954.

And here is another diagram showing the arrangements in 1924, when both platforms were south of the road bridge.

Interestingly at that time they were shown as an island platform, so one wonders exactly what was done when one of the platforms was moved north of the road: Was it the original platform 6 that was taken out of use and the original platform 5 renumbered platform 6, or was the platform south of the road completely rebuilt?
