In Adam Trimingham's article "What we need is a railway revolution" (The Argus, March 22) he argues for additional and reopened track.

This would help not only minimise disruption due to engineering work but to prevent blockages of the main line.

However, what we really need is more reliable trains.

Three times recently, trains I have tried to catch have been cancelled due to "a fault on the train" and I predict that, as the Electrostars get older, this will become more of a problem.

The old slam-door trains never broke down. Modern and gimmicky does not equate to reliable.

The 319s (the Thameslink rolling stock) do not need a GPS system to tell the driver which doors to open.

Thameslink has refurbished some of its trains but what is needed is for every available 319 to be obtained and refurbished.

They have superior reliability and could be used for many more years until somebody designs a train which is reliable, spacious, comfortable, has adequate luggage space, is cycle-friendly and has toilets which are not locked out of use when 80 per cent full or unavailable when the train breaks down.

Something like the old, Mark 1 slamdoor trains would do nicely.
