I remember a couple of trips to Kent in their very early days, when amongst the usual diet of CEP/CIG/VEP they were quite a novelty.
In those days it was possible to do, and indeed I once or twice did, GN to King’s Cross, Victoria to Margate via Chatham, spend a few hours in Margate, Margate to Charing Cross via Canterbury West and Maidstone East, then home from KX, all four trains being brand new 365s, still with that “new train” smell. In their early days first class had curtains, which along with the green colour scheme produced a very calming atmosphere indeed.
I forget how long the 365s lasted on the Ashford route, but it wasn’t long before they were concentrated on the Chatham side, doing mainly Victoria to Dover / Ramsgate. I’m not sure if they still did any occasional work via Ashford after that change.
The hybrid NSE / Connex livery suited them well, especially when clean. Had more been ordered then it’s almost certain the fleet would form the Kent Coast fleet for some years to come.
Now all in the bin simply because the DFT’s civil servants made a mess of things.
