Drafted-in to replace yet more steam on local colliery and branch trips, Haymarket got its first real taste of the Class 24's younger, bigger sisters in December '66 with the arrival of D7602-7608 from Barrow Hill.

These displacements followed their Clayton shedmates' transfer (effectively to the Millerhill subshed) by a couple of months, giving an instant north Derbyshire feel to Lothian freight. I can't even imagine what that might have been like.

The entire batch seems to have predominated on branch workings. I have footage of one at Auchendinny with a paper mill trip. On Waverley images there are positioning moves featuring these locos - famously the SO light engine working Hawick - Millerhill taking the Hawick pilot back home, and a beautiful study of another L/E at Stow - quite possibly the outward working of the same Saturday 'as-required' move. Pictures of them in the freight-only period are, thanks to Bruce McCartney, well represented. It is my contention that several of these locos worked as far as Hawick in normal service, and in 1967 I'm not ruling out their use, paired with other Baby Sulzers or piloting inter-regional freights, particularly the car trains, along the whole length of the route. Anyone wishing to model this niche genre of Waverley trip loco would be advised that the septet kept their smutty TTGSYP as-built livery throughout their ScR tenure.

As with Class 20s, there are several recorded incidents of Kingmoor poking 52xx Class 25s up the Langholm branch, and Derby Sulzers site records many whole-line episodes, principally with Glaswegian or Crewe rats.

A month or so after the last freight ran on the freight-only Waverley to Galashiels, St Boswells and Hawick, the same group were loaned to D16 (Toton) and formally reallocated there in July 1969. 7605 became an early accident victim, withdrawn in March '72.
