Seems peculiar, are 395s even cleared to travel as far west as Reading? Even if we were talking about Old Oak/North Pole here, which may very well not be the case, it still seems strange that a 395 would be there instead of at their dedicated depot at Ashford, or even the new Eurostar depot at Ebbsfleet, seeing as North Pole depot is now defunct. Why would a 395 have a reason to be so far away from its’ dedicated depot, which has the capability to undertake most maintenance and repair on the units, for so long?
Admittedly a 395 would be a much more likely candidate to confuse with the non-existant Hitachi Super Express than a 180, but other than that this sounds like quite a sensational report. This sighting being the 180 at Old Oak would be much easier to get my head round!
