Elderslie Fly Under

Location type


Name and dates

Elderslie Fly Under (1869-1983)

Opened on the Greenock and Ayrshire Railway.


West of Elderslie station was a flyunder which allowed a train from the station's slow westbound line to pass under the Ayr mainline to reach Cart Junction and then proceed to Greenock Princes Pier or south via Kilbarchan.

This avoided conflicting movements. For example a train from Paisley Gilmour Street to Ayr could simultaneously leave the station while a Paisley Canal to Greenock Princes Pier train left.

The route ran from Elderslie Junction to Cart Junction using the route of the former Glasgow and Ardrossan Canal where it was crossed over by the Glasgow, Paisley, Kilmarnock and Ayr Railway in 1840. The canal was long closed by the time the fly under was built.
