I have been looking for the MTH PRR A5 0-4-0 for years because it is more scale size than my K-line version (also Lionel's). The A5 in this catalog looks like it might be MTH's version, although it is hard to tell. "All new product" and "wireless drawbar" make it sound like it is not the old K-Line tooling. Hopefully someone can confirm one way or the other.
ADDED: Saw Beth's comments on the catalog that it is MTH tooling.
I don't think this is MTH tooling although I would love to be wrong. The previous MTH models will have a 'new tooling' icon next to it like the 0-6-0 does. It's definitely the Lionel model images but that may be all they had to go with.
