Ace Trains

Ace Trains BR 8P 71000 Duke of Gloucester

Reviewed by Martin Bloxsom and Richard Holder

Back in 1958 (60 years ago as I write), as a schoolboy I holidayed in Kent with relatives, travelling back from Euston to Rugby on the Mid-day Scot. I fondly remember one journey behind 71000 on this well-known train, the loco being very clean. I saw the engine several times over the years.

The valve gear

We now have an ACE Trains model of the loco, for 2 or 3 rail pick up, wheels at 27.8mm B/B, and able to traverse 2ft0in radius curves with all driving wheels flanged. If running on 2-rail, it is recommended that the 3-rail spoon collectors are removed. Conversion to stud contact would be easily achieved using the same fixing holes for a skate plate pick up. The 12/20 volt can motor has a brass flywheel and runs very freely.

*accounted for by loco/tender overhangs at cab/footplate/tender chassis.

Running on Richard’s line with 3ft 6in curves, including starting on these, a load of six ACE coaches weighing 12lbs was easily accomplished. Stopping needs some care to avoid over running a stopping point. A load of five heavier Exleys at NARROG at Harringworth needed similar care. We have little doubt that the model would pull double these loads. Current consumption is around 0.75A on level track.

Some details are missing, but uniquely, the Caprotti gear rods rotate prototypically, unlike some much more expensive models. The gear is quite robustly constructed but probably worth taking care when handling the model. Sprung buffers, lit front headlamps (express passenger code), opening cab roof ventilator, and correct balance weights on the driving wheels are fitted, along with the network of piping and plumbing. The tender lamp brackets are rather chunky, but accept ACE lamps. Apart from the lack of brake gear, the model is well detailed. The revolving Caprotti gear can be seen in action in a short video clip on the ACE Trains website and is well worth a look. More details could be added to the cab interior.

The tender has a coal pusher similar to that on the ACE 9F. A little coal dust would improve the appearance of the tender as would the addition of heating pipes and AWS gear on the front of the loco.

Three liveries, 50 of each version, will be produced, one each of the earlier and later tender crests and one with BR type, cut out metal cabside numbers. The cost for all versions is £825 and early ordering is recommended.

This model is certainly the equal of the ACE 9F and if anyone decides to modify one to 2RFs, it would be great to hear about it in the Gazette. ACE plans for the future include a variety or SR/BR King Arthurs and these will be advertised in due course in the Gazette.
