On a scale, the three classes weigh in as follows:
- 49 Class, 271g
- 48 Class, 260g
- 47 Class, 251g
- 13 FWH (Tranorama) wagons + van. Weight of 1097g, a "scale" tonnage of 895 tonnes.
- 9 WTY (Auscision) wagons + van. Weight of 920g, a "scale" tonnage of 753 tonnes.
- 10 WHX (AR Kits, weighted approx 82g per car) + van. Weight of 903g, a "scale" tonnage of 744 tonnes.
LATE UPDATE: Felt compelled to try to give an 8 car rake of Austrains WHX cars (151 grams/each) and a van up the grade, and it just managed. . . 1208g plus the van. . .these roll quite well also.
Curious: anyone know the tonnage rating of a single 48 class on the 1:40 Ardglen grade? I'm guessing the model is pretty comparable.
