Isle of Man Railways operate three heritage railways; the Steam Railway, the Manx Electric Railway and the Snaefell Mountain Railway. In total the length of all three Railways is some 35 miles. Burroughs were commissioned to undertake a programme of Principal Inspections across the network, comprising 90 rail structures.

The structures included under track culvert crossings, over bridges, under bridges, viaducts and retaining walls. The culverts varied in size and length, up to 2m in diameter and 30m in length. The bridges were constructed in a number of forms; masonry arch, cast iron trusses, steel beams and either carried the railway over road or glens or carried the roadway over the rail. Retaining walls varied in size, up to 10m high and 600m long. As well as requiring work at height, in confined spaces and adjacent to operational railways many of the structures were in remote locations and were difficult to access via conventional equipment.

Inspections were recorded electronically on a BMX asset management system, with prioritised repairs, indicative budgets, and future monitoring regimes.

Burroughs was also appointed by the Isle of Man Railways to design refurbishment of the rail crossings.

Burroughs reviewed the typical existing crossings and produced a number of designs, specifications and standard details that could be applied in combination to refurbish any configuration of crossing. These accounted for varying road widths, differing rail sections and gauge, drainage and service requirements.
