[17] Trains were limited to 20 miles per hour (32 km/h) on the branch due to some of the severe gradients, although some were levelled out by the LNER in 1942.

Even so, the sidings at Walkerville could only be shunted from 'down' trains (those travelling to Catterick Camp from the Richmond line) because of the steep gradient there.

[19] At the peak of services in 1927, sidings off the running line apart from the Camp Centre station were located at Walkerville, Arras, Helles, Messines, Vimy, Cambrai and Hipswell, with others leading to a power house, or general transfer sheds.

[20][21] One of the sections radiating away from the running line was used by the School of Railway Artillery for rail mounted guns.

[24] The line had several crossings, with most being ungated and needing watchmen to stop traffic whenever a train approached, as it had been constructed on the principle of being a light railway.

[27] In 1951, a direct through train to Birmingham was introduced on a Friday afternoon, and though initially not heavily subscribed, the service continued throughout the early 1950s.

[29] The prospect of the railway's closure led to questions in Parliament about patronage of the service and the financial renumeration of this to British Rail.

[1][35] After closure, whenever the Queen was visiting Catterick, the Royal Train would be stabled at Bedale railway station on the Wensleydale line.

[37] The railway bridge over the river at Brompton-on-Swale was re-used to carry pipes over it, but had a new deck installed in 2012, so it could become a pedestrian route.
