Airdrie Bathgate Project

Passenger services between Bathgate and Airdrie are due to commence in December 2010.


Platform numbers at Bathgate should read: Up Line P.1, Down Line P.2

Mileages are referenced from zero mile post at High Street (Glasgow)

Description of Scheme

The Airdrie - Bathgate Rail Link project consists of the re-opening of approximately 14 miles of former railway between Airdrie and Bathgate. The re-opening of the line will accommodate a new passenger service from the current North Clyde network to Edinburgh via the new line to Bathgate and on to Edinburgh via Newbridge Junction.

The scheme consists of a double line (Up & Down Bathgate) between Airdrie and Bathgate. An emergency crossover will be provided at approximately 13 3/4 miles near Caldercruix. Three new stations designated ARMADALE at 22m 1201yds, BLACKRIDGE at 20m 637yds and CALDERCRUIX at 14m 1320yds will be opened, each with an up and down platform. Each platform will accommodate a 6-car multiple unit train. The existing BATHGATE and DRUMGELLOCH stations will be relocated to 25m 396yds and 11m 1561yds respectively, each with an up and down Platform. All platforms are 150 metres long.

At Airdrie a new Up platform 150 metres in length designated Platform 3 has been created.

From Bathgate to near Drumgelloch the line is controlled from workstation 5 at Edinburgh SC (signals prefixed EN). From Drumgelloch to Airdrie the line is controlled from the East workstation at Yoker SC (siganls prefixed YS). To the west of Airdrie station the lines will be known as the Up and Down Airdrie and to the east the Up and Down Bathgate.

At Bathgate a new Light Maintenance Depot (LMD) has been constructed. The LMD can be accessed from either the east or west

The line speed between Newbridge Junction and Bathgate will be increased at the time of commissioning. For track layout on this section, see Signalling:Bathgate Branch 2008.

The project has also provided 25kV overhead line electrification from Haymarket to Airdrie.
