NOTE:  brake beams/shoes parts are designed to fit SMMW trucks but may also fit trucks from other manufacturers.  We know that the 50-ton part fits SHS PRR/Betterndorf and AM with 5'6" wheelbase.  Be sure to verify your truck's bolster is no wider than .200", has the correct wheelbase to fit 50-, 70- or 100-ton and correct wheel diameter (33" for first two; 36" for 100-ton truck).

It is the customer's responsibility to match our parts to your trucks.  No refund will be issued for SMMW parts that won't fit YOUR trucks.
Sn2 Truck Kits
First introduced in 2007 (freight trucks) and 2010 (Jackson & Sharp Co. truck), these kits were redesigned in September 2020 to combine many small, cast urethane pieces into larger parts that are 3D-SLA printed.  In October 2023, the J&S truck was redesigned as a single printed part including the end beams and characteristic strap springs. 

The freight trucks consist of (3) pieces:  sideframe-bolster-journal lids being (1) piece with (2) new brake beams/shoes parts.  Not all "2-foot lines" operated trucks with brake shoes hung from the sideframes ... some were body-mounted ... so you can model just about any variation.

Trucks can be purchased with or without Kadee HOn3 wheelsets.  All trucks include #0-48 x 1/4" screws.  Passenger trucks include Kadee #637 springs (for appearance only).
"Common" Truck
Trucks are fully sprung kits unless otherwise noted.  These consist of 3D printed sideframes, bolsters, journal box lids and brake beams/shoes, pre-assembled wheelsets, springs, and screws.  Bolsters and sideframes include locating "posts" to easily position springs ... spring load keeps them in place ... no glue required.
