Hastings - Ashford Railway: BCL Films 1987 Documentary: Part One. 

Here is part one (of two) of an excellent, professionally produced, documentary film about the Hastings to Ashford railway sometimes called the "Marshlink" made by BCL films of Hastings in 1987.
Here is an extract from the notes on the original video cassette box:
This is a detailed film of the Hastings to Ashford line, including the Dungeness branch, and a look at what remains of the Rye Harbour branch. From Hastings the line runs alongside the Fairlight Hills through the Sussex Weald. On through the halts of Three Oaks and Doleham it continues along the valley of the River Brede, exploring the long closed halt at Snailham before reaching Winchelsea and crossing the River Tillingham into Rye. At Rye the film makes a detour to explore the Rye Harbour branch. Leaving Rye across the River Rother the scenery changes as the line crosses the edge of Romney Marsh. Arriving at Appledore the film again makes a detour, this time onto the Dungeness branch, and the nuclear flask train at the power station. After Appledore the line crosses the Royal Military Canal near Warehorne before arriving in Ham Street. From Ham Street the line runs up through a dip in the hills to arrive in Ashford past the old railway works at Chart Leacon.
Part two (separate upload) shews mainly a round trip over the line on board Hastings DEMU No. 203 001 (formerly No. 1011): it also shews some of the many variations of DEMU formation in use on the "Marshlink" in the late 1980s.
This film is copyright to BCL films and shewn here without permission BUT, as far as I can tell, BCL films no longer exists (cannot be found on the internet) and, as far as I know, this footage is not available to be purchased or seen either via the internet or locally. Therefore, I beseech the forbearance of the copyright holders - the tape that I have (VHS video cassette) is deteriorating and if I don't digitise it now it will not be possible to watch it for much longer. My only objective in posting this here is that I and other people who share this interest can continue to see this historic footage in the future.
