Good idea.
I wonder - would Hastings vis Ashford on a 395 be much quicker than via Tunbridge Wells?
It could be a whole new riviera... Rye would boom, I imagine.
St Pancras - Ashford 37mins
Ashford (waiting in station) 1min
Ashford - Hastings 35mins (using data from Network Rail route specifications based upon a predicted line upgrade to 75mph and stops at Ham Street, Appledore and Rye with 171s)
St Pancras - Hastings 73 mins (the time saving of 395s rather than 171s and potentially not stopping at Ham Street and Appledore means that this value in reality would be smaller)
London Bridge - Hastings 83/95 mins
Charing Cross - Hastings 91/103 mins
I would have a guess that a 395 would do Ashford to Hastings in 28 mins with the 75 mph speed limit and only stopping at Rye. That would mean a 68mins journey from St Pancras to Hastings. The line looks straight enough to have a higher line speed.
However, many of these benefits could be produced by upgrading the Marshlink (including double tracking and electrification) and providing a 4 minute connection at Ashford. The connection could be guaranteed by having one train wait for the other if it is late. The Marshlink service could then be advertised as 'Ashford Int (for London St Pancras)' when the service is in Bexhill and to the east of Bexhill. It would benefit Bexhill more than Hastings, reducing London journey times from 110mins to 77mins. A stopper could run between Eastbourne/Hastings and Ashford to provide the small stops along the line a service and to provide 2tph for London form Hastings with a change at Ashford.
There is also the possiblity of bringing back proper express services between Hastings and Charing Cross via Tunbridge Wells. The Kent RUS reccomends running all peak services between Charing Cross and Hastings fast between London Bridge and High Brooms with the train dividing at Tunbridge Wells into a fast and and a slow service. It also suggests that this style of service could run all day. Though it does note the possible adverse effects on East Coastway services. The RUS assumed that the power supply between Tunbridge Wells and Hastings could not handle 12-car trains. However, a limited number are now running in the peak. I also think that there needs to be a direct service between Hastings and Tonbridge. I would suggest altering the idea by running the following services instead:
- Service 1
- Charing Cross
- Waterloo East
- London Bridge
- High Brooms
- Tunbridge Wells
- Frant
- Wadhurst
- Stonegate
- Etchingham
- Robertsbridge
- Battle
- Crowhurst
- West St Leonards
- St Leonards Warrior Square
- Hastings
- Service 2
- Charing Cross
- Waterloo East
- London Bridge
- Tonbridge
- Tunbridge Wells (Train Divides)
- Front
- Battle
- St Leonards Warrior Square
- Hastings
- Rear
- Frant
- Wadhurst
- Stonegate
- Etchingham
- Robertsbridge
- Battle
- Crowhurst
- West St Leonards
- St Leonards Warrior Square
- Hastings
This would provide 2tph to all stations on the Hastings line. It would also mean that Battle, St Leonards Warrior Square and Hastings would have two fairly fast trains per hour to London.

One would notice that my 'service 2' is very similar to what the 'Hastings Diesels' ran.
