Thanks to the tip-off by Diamond Geezer last week, today I travelled on the 10.02 Southern 'Parliamentary Train' from Kensington Olympia to Wandsworth Road.
As described by DG, it is indeed a weird feeling to board a train when the public address system explicitly tells you that the train is not in public service.
That would be me and a couple who like me, seemed to be on the train simply so as to make the journey that has no real purpose.
We left on time, called briefly at West Brompton and Imperial Wharf, before passing over the River Thames and then crossing a maze of railway junctions, somewhere South of the river.
We stopped for seven or eight minutes adjacent to the carriage works for the Venice Simplon Orient Express, before eventually pulling into Wandsworth Road station a minute early at 10.19.
If the point in travelling is the travel, then the journey was a short success. If the point of travel is to get to your destination, in this particular case, I wouldn't bother, but then I virtually need to use my passport when venturing as far South as Wandsworth.
I did travel North from Wandsworth Road, but back to Victoria. However I note that Ian Visits has previously made the afternoon return trip on this rather unusual, once a a weekday there-and-back train service.
