)Yes, so really the answer to the question is to find the station with the narrowest single island platform.
I'd nominate one of the Glasgow Underground stations, although as they are below ground level, the circumference of the earth will be slightly less...

Abergele & Pensarn station on the North Wales coast is pretty wide between platforms..
This appears to be wider than Farnborough Main which Google measures in at 23.2 mtrs.Good call, that (was) four tracks and a signalbox wide, and seems to get wider towards the road bridge. Google Earth says its about 23.5 metres.

Beaconsfield must have fifty feet between the two platforms.
As long as it is consistently inaccurate, it'll do as a comparison tool![]()
Hasn't Beaconsfield been ruined, err rebuilt, with a platform extension onto the trackbed, making it impossible to re-instate an up passing loop there now?
But it is not consistently inaccurate. It is relying on people to click accurately on either edge of a low resolution photo which was taken from a plane. Dont get me wrong, it is a brilliant brilliant tool and it is great at giving rough estimates at distances but it far too imprecise to say whether one 25 metre gap is slightly larger than another 25 metre gap. The tolerances are just too big for that.


I think you missed the smiley! What would you suggest we use instead - a tape measure?![]()
Is there a standard gap required?
Abergele, Farnborough, Cheam; all 23-24m?
