I'm a big fan of the LGB Toy-Train range. Reasonably priced, rugged and colour ful rolling stock that looks nice in the garden and will take the odd spill when you are testing the railway after a long lay-up. It's also cheaper than the main range, especially if you manage to bag some second-hand.
That's how I acquired the wagon above. We don't have a tanker, and this one has my Dad's initials on the side too, so for £25 I picked it up from Exeter. The only downside is, it's a bit grubby, but that is fixable.
German engineering, even for "Toy Trains" means the whole thing can be taken apart with a scredriver. The wheels are sprung out from the swivelling (LGB stuff is designed to go around stupidly tight curves) axleboxes and then these are turned to give acess to the screws.
A few minutes work and the wagon is reduced to its component parts. These than head to a nice sink full of soapy water for a good scrub with an old toothbrush followed by a long rinse in cold water.
The wheels show evidence of plenty of use but I'm not worried about this. Water has obvioulsy got into the axleboxes and corroded the axle ends. Nothing a light sanding with mild abarasive paper can't take care of though.
After this, rebuilding is the reverse of dismantling and the wagon is nearly as good as new.
