Purchased BR heavy haulage and so far very disappointing. Class 47 oil train out of Manchester only does 13kph and does about 30kph on the "gentler" inclines. The disappointment comes from the advertising showing dual locos which to my search, there are no scheduled services with dual locos. The whole point of getting this add on was to use dual locos. Even the class 50 struggles with empty oil wagons.
