Which version of Trainz are you using?? I'm not that well up on US locos, but there is a built-in Vanderbilt tender in TRS2004 and I think 2006 as well. It is by Austin316hockey and I think it applies to the built-in CN U2g also by Austin316hockey. I may be totally wrong, if so, I apologise,and plead insanity.:hehe:
