The British Rail Class 45 (aka ‘Sulzer Type 4) were a fleet of diesel locomotives, nicknamed ‘Peaks’ along with the similar Class 44 and 46 locos. The class became the main motive power on the Midland Main Line from 1962, allowing for considerably quicker services over the previous steam powered trains. The class continued working on the MML until the early 1980s when they were relegated to secondary services following the introduction of HSTs to the line. Later in their lives, the class plied their trade on North Trans-Pennine workings. 26 of the class were named after British Army regiments and the Royal Marines. Additionally, several were unofficially named.
