Happy Birthday Jay, nice to see someone else buying HO (or O) gauge trains and rolling stock. I got hold of a couple of Mantua's the other day I have to say I loved the construction quality and detail on those. I have a similar model to the Rivarossi you got as well, but mine was branded 'Airfix' (yes the model maker), but manufactured by Bachmann.
Do either of those loco's have any special features, you know lights, smoke, etc..?

Happily collecting things all my life...
