The Eastern Counties Railway arrived in 1842, but due to the geography of the town, an 18-arch viaduct had to be built across what is now the town park. The station was built on a viaduct in its current location, so the platforms are above street level.
Unusually for a town of Chelmsford's size there is just one railway station. Chelmsford railway station is virtually in the centre of the town and around 10,000 commuters travel to London daily by rail. Outside of London, it is currently the busiest completely non-terminus station in the UK.
For many years, a second station has been proposed on the north eastern fringes of the town at Springfield in order to serve the expanding housing developments there - so far nothing has come to fruition.
The present station building dates from a rebuild in 1985.
Stealth required as at most times this will be a busy muggle area.
