Its a damp March 10th 1962 as D5121 stands at Inverness with its train for a Far North or Kyle service. D5121 has been in service for about 21 months, the tablet catcher has been fitted and the roof mounted boiler water tank filler cover is still in place, but not fitting too well.

D5120 & D5121 were northbound at Aviemore with a service for Inverness on April 1st.

An SRPS special on June 19th encountered difficulties whilst returning from Inverness. The train had been worked up from Glasgow by 5360 & 5372, and these were used for the return. Unfortunately 5372 failed leaving Dalwhinnie, stalwart 5360 soldiered on alone over Drumochter only to expire at Dalguise. Rescue came from 5117 & 5121, fresh off the “Royal Highlander’, pushing the train to Dunkeld, where further assistance appeared in the unlikely shape of 415, a class only recently cleared over this route. Travelers on the special finally reached Glasgow 160 minutes late.

On May 12th Glasgow Works held its first Open Day, remarkably there were sixty four diesels on display that day, although twenty seven of those were condemned Claytons. Two class 25s were present, 5178 and 5157, the latter having a replacement cab fitted from withdrawn 5149. Class 24s noted were 5006/19, 5121/27 under repair and elsewhere withdrawn 5067, 5114/49. Parts of 5068 were still present.

On June 26th 5121 worked the 17.50 Kyle of Lochalsh - Inverness service.

During August Inverness Type 2s were frequently diagrammed on freight or parcels services to Berwick & Newcastle, so noted was 5121 with a Millerhill - Tyne freight on August 7th whilst on 8th 5115 with an Edinburgh - Kings Cross parcels to Newcastle, returning north with a Kings Cross - Edinburgh parcels.

On August 6th 24121 worked an Inverness - Kyle of Lochalsh service.

On August 16th the 11.08 Kyle of Lochalsh - Inverness with 26029 failed just east of Strathcarron station, the train was able to reverse into Strathcarron loop and await rescue. This issue delayed the 10.36 Inverness - Kyle of Lochalsh with 24121 by about half an hour. Eventual rescue came in the shape of 24118, which took the failed locomotive and train to Inverness, arriving about two and a half hours late!

On August 18th 24121 was noted at Muir of Ord with a mixed freight.

The Glasgow Works Open Day on May 17th included 24117 & 24121 receiving attention.

24121 was noted at Inverness depot on August 6th.

The 17.10 Edinburgh – Berwick continued to run with a wide variety of power, on December 29th 24121 was utilised.

24121 worked the 07.20 Aberdeen - Glasgow Queen Street on February 28th.

April 6th found the double headed 16.35 Inverness – Glasgow Queen Street in trouble at Kingussie when leading locomotive 26034 failed, being removed and replaced by 25029 off a northbound freight. However 25029 was later detached at Stirling after parts from it hit a freight train near Dunblane, leaving 24121 to carry on alone reaching Glasgow two hours late.

On September 8th was noted running light at Edinburgh.

On October 9th 24121 was noted with mid-morning empty coaching stock at Perth.

By October 22nd all the remaining ScR Class 24s were officially stored at several locations, the majority (at least fifteen) at Millerhill, leaving the remaining eleven active LMR members all based at Crewe. However their retirement was not entirely because of their unserviceability. 24121 was revived from store at Polmadie on October 22nd to work the 1A53 17.12 Glasgow – Ayr passenger service due to a death on the tracks disrupting the regular diesel multiple unit services.
