Thomas Grainger

Their firm operated from the ground floor of Grainger's house at 56 George Street, in the centre of Edinburgh's New Town.

[1] Between 1845 and 1849 his company worked on the digging of the Bramhope Tunnel and building the Arthington Viaduct as part of laying the Leeds to Stockton-on-Tees line.

The first modern rail ferry, the Leviathan, was designed in 1849 by Grainger for the Edinburgh, Perth and Dundee Railway to cross the Firth of Forth between Granton and Burntisland.

[6] He died in Stockton-on-Tees on 25 July 1852 as a result of injuries sustained in a train collision two days earlier.

One of two fatal casualties, Grainger had sustained a compound fracture to his right leg, which quickly turned gangrenous.
