Traction Tires for Diesels and Electrics?

[Trolleyfan]

You can get lead putty from A-Line/Proto-Power as their item number 13010 but their website says it's out of stock right now (8/27/2009). Being a putty you can pack it into all sorts of nooks and crannies in the chassis and body. I used this on a project in HOn30 to add enough weight to a very small locomotive (critter to some) that I built from a Nigel Lawson etch kit of an O&K RL1c. The loco is just over an inch long, barely over 3/4 of an inch tall and just over 1/2 inch wide.

You can see some photos (not mine) and the actual dimensions of the loco here: http://www.nigellawton009.com/OandKRL1cMontania.html
