THere used to be a late evening train out of Derby to Glasgow from London which must have travelled pretty late at night though I dont know much about it.
1S24 2130 St Pancras - Glasgow Central which attached 2 sleepers at Nottingham (dep 2354) and ran via Derby (dep 0026), Sheffield, Leeds, the S&C and the GSW (i.e. via Annan & Kilmarnock). The return was 1M98 2350 Glasgow Central - Nottingham (which I used frequently) as it left Derby at 0618 and got me to work in time for the 0700 shift. Rarely was there more than a handful of passengers on it but in the winter after a long cycle ride into Derby it was like heaven, the steam heat coaches being toasty warm.
This train is traceable back to the 1930s when it ran from Euston to Glasgow St. Enoch via Northampton and Market Harborough. Sometime in the 80s it lost its passenger accommodation and became 3S24 2330 Leicester-Glasgow parcels, then it became 3S24 2330 Nottingham - Glasgow parcels and finally 3E00 2354 Nottingham - Leeds parcels.
I worked in Nottingham control, Derby PSB and Trent PSB from the 70s through to the nineties and a summer Friday night was the busiest night of the week with all of the west country holiday trains and oddities like the 0030 Sheffield - Portsmouth via Nottingham and the MML, a Nottingham - Newquay via Leicester and Nuneaton, and a Leeds - Bournemouth via the MML.
My most enduring memories of that time though surround 1M10 2359 (Mon - Fri, 0010 Sun) Sheffield - St. Pancras. The station allowances for parcel & mail working were extremely generous and it took no less than 5 hours 20 minutes to run from Sheffield to London. I caught it frequently and it was well used, even in the week, arriving Derby at 0046 and departing at 0115 arriving into a deserted St. Pancras at 0519. On Sundays it took even longer often being diverted via Leicester (RR) Melton, Manton and Corby then back onto the main line at Glendon North. What with that and SL working in the London area a St. Pancras arrival at 0700 (6 hrs 50 mins journey time) was not unusual. Compare that with the fastest train today being around two hours for the same journey!
The return was 1E03 0005 (Mon - Sat, 0030 Sun) St. Pancras - Sheffied which was much quicker than its southbound equivalent. Running via Nottingham and Derby it only took 4 hours 30 mins!
I could go on - 1M58 2030 (I think) Peterborough - Crewe mail/passenger via Leicester and Derby which combined with 1M77 2000 Lincoln - Derby main/passenger and returned as 1E74 0044 Crewe - Peterborough detaching a Lincoln portion at Derby to form 1E88 0222 Derby - Lincoln mail/passenger.
They all lost their passenger accommodation sometime in the late 70s early 80s and ran for years after that as mail trains.
Then there was the wonderful 2P85 2239 (Mon- Fri) Nottingham - Derby loco-hauled and loading up to sometimes 16 vehicles. Basically it was just a stock balancing exercise conveying two stock circuits from Nottingham to Derby for changeover plus odd parcel vehicles. It returned as 2D85 0125 (Tue - Sat) Derby - Nottingham which again conveyed as many as 16 vehicles. Frequently there were no passengers at all on the 0125 but the 2239 from Nottingham was busy, if only with rail staff coming off shift at 2200!
