I purchased the Bachmann 3 wagon set & on the strength of that also went a head & purchased the TMC 6 wagon set. On closer inspection I noticed that if you look at the wagons with the end discharge door positioned to the right, on the Bachmann 3 wagon set you can't see the brake rigging (as it's on the far side of the wagon), but on the TMC 6 wagon set you can see the brake rigging.
From a quick search of the net for pics of 16 ton mineral wagons, it would appear that the 3 wagon set have been assembled correctly, but the TMC set have had their tops put on the wrong way round ie turned through 180 degrees.
Can anyone confirm that I'm right before I go & alter the 6 TMC wagons?
Cheers, Mike C
