The main building of the station, which housed the booking office, parcels facilities, staff facilities and the stationmasters' house, was on the Sheffield-bound platform and was built in the MS&LR "Double Pavilion" style, one of the earliest examples, whilst the Doncaster-bound platform had to suffice with a plain brick-built waiting shelter.

On closure these facilities were bought by Thomas Hill (Rotherham) Ltd, a subsidiary of Rolls-Royce Limited, who built and repaired industrial locomotives.

The Kilnhurst stationmaster had control over rail traffic and staff in an area which covered the local pottery and brickworks from the earliest days, and following their sinking collieries at Piccadilly and Kilnhurst (both accessed from the brickworks' branch) and Silverwood, accessed from a new, steeply graded line, built jointly by the MS&LR (GCR from 1899) and the Midland Railway.

One unusual siding over which he had control was "Thrybergh Tip", a short spur off the Silverwood line which was a dumping ground for Sheffield Corporation sewage.

In 1959 at the request of the local Working Men's Clubs at Thrybergh a short, about 75 feet (23 m) in length, platform was built near the Park Lane bridge on the Silverwood line to serve the "Children's Outings" - seaside day trips for members and their children which were a regular feature in the clubland calendar.
