Surprisingly, I don't recall that many 45s on freight on the Gloucester line in the 1960s, they seemed to stay steam hauled (4Fs, Black 5s, 8Fs, 9Fs) until about 1964-5, and then move straight on to Brush 4s and a surprising number of EE 3s (47s and 37s for our younger readers). The 45s did dominate passenger workings, apart from summer Saturdays, from quite early on, maybe by the end of 1961, with the odd Jubilee still here and there. Steam on WR freight through Taunton was pretty much cleared out by the arrival of the Hymeks by 1962, but these didn't work north of Bristol. I think the Bristol-Birmingham line was an early candidate for BR pattern AWS, whereas west of Bristol had longstanding GWR ATC, locos were not dual fitted, a lot of the power of the Birmingham line stayed LMR types (both steam and diesel), so there was long a definite divide at Bristol.
I've just found my logbook for that day. It was 08 September, 1965.
Didcot MPD - 7904, 6928 (probably dumped)
Swindon - Gloucester - D826 (probably on shed? I don't think Warships worked to Gloucester) D7028, D 1680, D1025, D7023, D7064, D3108, 15100 (Southern shunter???), D2194, 4100 (2-6-2T?), 45392, 44264, 6160, D3992, 6113
(So still three GWR 2-6-2Ts - I can't remember these at all. I do remember the lovely scenes as the train wound itself out of Savernake Tunnel, however.)
85B Gloucester Shed (I forget if it was the ex LMS or ex GWR)
D6954, 82040 (Taunton has difficulties appreciating these lovely Standard 2-6-2Ts
), D1614, 92219, 82042 (another one!) 8745, 6857, 7814, 3643, 78006, D1667, D178, 92129, 80037, 41291, 92230, D3993, D2196, 48651, 3823, 4698, 3816, 92000, D1744. 82039 (oh, another beauty!), 44269, 90037, D1668, D4168, 6965
As I typed these out, I am staggered by a) the number of locos on the shed and b) by the variety. I had completely forgotten how many different classes of locos were there! A Grange, a Manor, several GWR 2-8-0s, an Ivatt 2-6-2T and not to mention those lovely Standard tanks
. wow, we were still so rich in variety at such a late stage. I had forgotten.
Now, these are my spottings after returning to Gloucester Eastgate. This would have been from approx 12.00 noon to approx 15.30.
92213, D1656, 4689. D1697, D6914, D2138, D1815, D1661, 48291, 1693, 7802, 76039, D1651,
92231, D123, D37, 70024, D1615, D136, 48393, 78004, D1609, D1700, 92247, D1036, D7033, D1067
Leaving Gloucester 6876.
What an absolutley amazing variety of motive power, and so late in the day - not including DMUs, of course!
Taking into account Taunton's thoughts, I suspect that the LMR's policy was to dieselise the express passenger workings first of all - thereby ridding the railway of expensive-to-maintain 3 cylinder passenger locos ( Jubilees and Scots) and then slowly whittle down the steam on freight. Notice too that there were quite few 9Fs working that day - relatively modern heavy freight locos.
BTW, ISTR that on my way back to Goring and Streatley (my aunt lived in the latter village) there had been a derailment on the down relief, and the sleepers were rather cut up by the errant waggon. This was somewhere between Goring and Cholsey.
