Amazing limited production model trains.

NP ‘Mainstreeter’ Power Set F3 A&B




These engines are NOT ‘sold out’. But orders are closed until we have a better understanding of the situation in China. New delivery date will post here as soon as I get it from InterMountain.

 This item is effected by the factory closure in China. Production is delayed and updates will be posted here as soon as we have them!

We appreciate your patience as we determine the best course of action.


InterMountian is producing these exclusively for Lowell Smith Signature Series and this Mainstreeter collection. The colors will match the NPRHA’s drift cards so these will go perfect with your Mainstreeter ‘Pine Tree’ train set. This pair includes F-3A & B , road number 6502. The B unit is marked as 6502B. The B unit in this set is a ‘dummy’ unit with no power mechinisim. 

The best news, is that you get to choose the type of power chassis for your set!

Choose below, DC, DCC or DCC with ESU LokSound! Quantities have been set so early reservations are very important to get your choice. When one of the versions is no longer available, it will not allow you to reserve that version.

To say the least this is a HUGE development for N-scale and I, along with a number of others, are indebted to you for making these cars possible. Thanks so very much!!!

Every new release from your Signature Series gets me revved up for the rails.


You know I’m always looking forward to the next release and its arrival with great anticipation. I treasure my Lowell Smith Signature collection.

Thank you for everything you’ve done and everything you do for the modeling community. I can honestly say that my enjoyment of the hobby has benefited greatly because of you.

I just received my Carolwood Pacific cars yesterday. They are exquisite! Every attention to detail was paid here, and I can’t thank you enough for putting this into production.  They are going to look amazing, circling my main Street miniatures display.


The thing I love about all the things you do is the fact that everything is so well thought out, so beautiful and so unique.

I received my observation/business car today and – like all of my other cars from you – I love it!


Thanks, Lowell, for another awesome addition to an already incredible train.
