Yep. Looks interesting.

Was it a good truck, generally?

When I was at the Bendigo Tramways we used to grease our curves with a 50/50 mixture of Mobil Crater #5 and used motor oil and boil them up in a wood fired cauldron. That stuff stuck to the side of the rail very well.

I never understood why the M&MTB didn't grease at least the tight curves.

The idea of a "Radiax" truck was that the axles could move a little to follow the curve. If they were not well greased, then that movement would be that much less flexible. I attach a pic of 180's Brill Radiax truck - you can see how the axle boxes are floating in the middle of a yoke like casting - with springs to hold them roughly in position. mal http://movies.yahoo.com.au - Yahoo!
