A ‘37’ AT 60
One of the oldest Class 37s has just celebrated its 60th anniversary at the Great Central Railway, the Heavy Tractor Group’s No. 37714 being the 25th-built member of the f leet but the 11th-oldest survivor, as Paul Bickerdyke discovers.
DESPITE its high number within the fleet, No. 37714 is actually one of the oldest Class 37s and on August 21 celebrated its 60th anniversary with a special day of running at the Great Central Railway. The first English Electric Type 3 No. D6700 (later Class 37 No. 37119/ 37350) had entered traffic on December 2, 1960, but No. 37714 followed just eight months later on August 25, 1961 as the 25th member of the class No. D6724. Like many of its hard-working and versatile classmates, the Series 1 machine (those built with a split headcode box) enjoyed a varied career around the country, spending time allocated to depots such as Stratford, Thornaby, Motherwell and Cardiff Canton. It became No. 37024 in 1974 under the TOPS renumbering scheme before being chosen as one of the refurbished ‘heavyweight’ fleet in 1988, which saw its headcode boxes replaced with a flat cab nose and central marker lights.
Beefed-up
British Rail had decided to refurbish its Class 37s in the mid-1980s as they were then a ‘mid-life’ 20-25 years old (even though some are still going on the main line today at 60!). This programme created a number of new sub-classes, one of which was the Class 37/7. These were given extra ballast weight to provide greater starting tractive effort for heavy freight work, the locos weighing in at 120 tonnes versus around 100 tonnes for a standard ‘37’. Class 37/7 locos chosen from the Series 1 fleet (the former Nos. 37001-119) were renumbered upwards from No. 37701, while those from the Series 2 fleet (former centreheadcode Nos. 37120-308) were renumbered downwards from No. 37899. These all had Brush electrical equipment, but a further eight refurbished locos were fitted with alternative GEC electricals, becoming Nos. 37796-799 (Series 1) and 37800-803 (Series 2) in the process. A total of 44 locos were eventually converted to Class 37/7: 23 from Series 1 and 21 from Series 2 (including the four from each series fitted with GEC equipment). Typical duties for them included steel trains around South Wales and the North East, as well as coal trains in the South Wales Valleys. By the time they passed into EWS ownership in 1996, however, many of their dedicated duties had been taken over by Classes 56 and 60, which were themselves displaced by new Class 66s from 1998.

Home and away
No. 37714 was briefly named Thornaby TMD from late 1992 to early 1993 during its time at the Teesside depot, then after passing into EWS ownership it received the operator’s red and gold livery in 1997. After being stored in October 2000, a new life beckoned working on railway infrastructure projects in Spain, being sent there at the end of May 2001 sporting GIF light blue livery – initially as No. L031, but then becoming No. L26.
It was repatriated to Britain via the Channel Tunnel in August 2012, becoming part of the DRS fleet a year later in August 2013 and finding use as a ‘super shunter’ at Daventry International Railfreight Terminal (DIRFT) from November that year alongside classmate No. 37703.
Using a heavyweight ‘37/7’ for shunting duties was never going to be ideal, however, which led to it being returned to Barrow Hill in November 2015 for attention, and while
there visited the Great Central Railway in March 2016 as a star guest at the line’s spring diesel gala.
It was here that the Heavyweight Tractor Group became involved. DRS had considered putting the loco up for sale, but decided to loan it out to preservation instead. The HTG was formed specially to take care of
No. 37714, and a loan deal was arranged that eventually led on to the group acquiring the loco at the end of 2017.
Life in preservation
Whilst still on loan at the end of 2016, the HTG took the loco by road to Loram, Derby, to be painted back into the triple grey livery it had received in 1988, the ‘newold’ look being publicly launched at the
Great Central Railway’s spring diesel gala in March 2017.
The group found the loco to be generally in good condition; some work was needed on the injectors, but the engine, bogies and bodywork were essentially sound. One bonus, especially for its use at the GCR, was the discovery that the vacuum brake equipment was all still in place. BR usually removed this in the 1980s refurbishment programme, the locos being returned to service with air brakes only. But on No. 37714 the vacuum brake system was simply isolated and the gauges painted over – probably left in place on purpose as part of the extra ballast weight added to the ‘37/7s’ – and it was a relatively straightforward matter to make it operational again.
The loco was officially named Cardiff Canton at Loughborough GCR on March 17, 2017 along with a plaque dedicating the loco to the memory of Paul Fairfax, who was instrumental in the introduction of the Class 37/7 sub-class to the South Wales depot in the late-1980s.
The loco has been based at the GCR ever since, its extra weight making it more expensive to transport by road to other lines. Longer-term, however, there is the prospect of more cost-effective movement by rail once the GCR and GCR(Nottingham) – the latter now renamed the Nottingham Heritage Railway – are reconnected via the reinstated bridge over the Midland Main Line and the main line connection at the northern end.
A true survivor
Of the first 25 Class 37s built, 14 have been scrapped (Nos. 37001/37707, 37002/37351, 37004, 37006/37798,
37008, 37010, 37011, 37012, 37013, 37014/37709, 37015/37341, 37019, 37020/37702, 37021/37715); six have been preserved (Nos. D6700/37119, 37003, 37009/37340, 37017/37503, 37023, 37034/37714); and five are still owned by main line operators (Nos. 37005/37601, 37007/37604, 37016/37706, 37018/37517, 37022/37608). This means No. 37714 is the 11th oldest surviving Class 37 and the sixth oldest in preservation.
Of the 44 refurbished Class 37/7 ‘Heavyweight’ fleet, just seven survive – five Series 1 locos (Nos. 37703, 37706, 37712, 37714, 37716) and two Series 2 (Nos. 37800, 37884). No. 37714 is the thus second oldest of these after No. 37706 (the former No. D6716/37016). ■
