Irongray was one of the principal stations on the Cairn Valley Light Railway branch, from Dumfries.

The station cost £212 to build in red brick with cream painted poster boards and chocolate-coloured framing.

[4] A station master's house was provided, designed by the company with a pyramid roof truncated by a central chimney stack.

[7] An electrical ground disc signal controlled the movement of trains from the siding onto the main line.
