There were 148 bridges in all, and three tunnels.
The rails were double headed in 15-foot (4.57 m) lengths at 77 pounds per yard (38.2 kg/m) at a gauge throughout of 4 ft 8 ¹⁄₂ in (1,435 mm) standard gauge.
These were laid either on gritstone blocks from Cromford, laid diagonally,  or on embankments, timber sleepers of oak or kyanised larch.
For a length near Rugby, Evans's dovetailed bridge rails of 57 pounds per yard (28.3 kg/m), were tried, mounted on longitudinal Memel fir timbers with pine cross sleepers.

The earthworks ensured that the maximum gradient of the line was 1 in 330 (0.3 %).
The largest were on the Rugby line at the Leire cutting and embankment.
The whole project required approximately 5,700,000 cubic yards (4,400,000 m³) of earthworks.
There were only two significant bridges and viaducts, one being that over the River Trent, which comprised three cast iron arches of 100 feet (30.5 m) each and the viaduct over the valley of the Avon (now Grade II listed) which consisted of 11 arches of 50 feet (15.24 m) each, elevating the line 40 feet (12.2 m) above the valley floor.

The total cost of construction was just under £1,400,000 (equivalent to £124,170,000 in 2018).
