It seems you are new to this forum. You will never get any help if you post the way you did this time. Firstly, large fonts and capitals are interpreted as shouting. Please don't shout. Secondly, the word "please" is as important here as anywhere else. Thirdly, you need to be much more specific about what you are looking for. Please edit or re-compose your post, and you will probably get the help you need.

EDIT - Well, it seems a few people are already trying to help you. See what a good place this forum is? Please treat it with respect.
Also bear in mind that this is an international forum, so you may have to be more specific.
If you're after UK 3rd rail locos, then there are class 73s in various liveries on the DLS. Whether they work in your version of Trainz I don't know, as you haven't told us what version you are using. This thread has a fairly comprehensive list (albeit a bit out of date) of what's available (mostly on the DLS - available stuff is in bold): http://forums.auran.com/trainz/showthread.php?t=8800
For Uk Third Rail try Kuid No.35412 in D/l Station.
There's track and also 4-CIG Electrics
I don't know wether they'll work for you as you don't state what Version you're running.
