As a regular commuter from London St Pancras to kent coast via HS1. The last 2 weeks everyday our train has been overcrowded due to short formation only 1 x 6 car unit instead of usual 2 units being available. Southeastern have blamed a shortage due to a unit out for repairs. Does anyone have any more details of which 395 unit is out for long term repair? When it is likely to return. Also why is it always the same diagram that is short? 17.55 st pancras to Broadstairs?
