I emailed auscision and they confirmed today that vans will come with interior details the same as ontrack, so if its purely on cost auscision is the clear winner with a 4 pack at $220 and a 5th wagon free that works out at $44 per wagon inc postage compared to otm $65 per wagon inc postage.Trainorama previously did these wagons as mentioned by a previous poster but they had chunky bogies and lacked detail and the roof profile was not correct compared to the more accurate models coming soon from auscision and otm.

Assuming no policy changes, Auscission will come with steam roller width wheels and Chinese scale head couplers, OTM will come with fine scale wheels and genuine Kadee scale head couplers. If you want fine scale wheels and Kadee couplers the price difference becomes minimal between the 2 brands. Time will tell which is the more accurate.
