MDC Roundhouse Southern Pacific 40' Truss Side Boxcar Review: Out-of-Production HO Car Worth Buying?

A close look at the MDC Roundhouse 1034 Southern Pacific 40' Truss Side Boxcar-an out-of-production HO ready-to-run car that arrives without its original box but with plenty of old-school character.

Last updated Aug 15, 2026

Quick verdict

If you model HO and want a boxcar with an older look, the MDC Roundhouse 1034 40' Truss Side Boxcar SP 29637 is a strong $11.95 option. It's factory painted and lettered, and it comes from an out-of-production line. The catch: this is a used car, and the steel parts may show light surface rust from age.

Who it suits

This car is best for adult collectors and modelers aged 17 and up who need a Southern Pacific boxcar for a layout or display. It also suits anyone who appreciates the look of vintage HO freight cars.

At a glance

MDC Roundhouse 1034 SOUTHERN PACIFIC 40' Truss Side Boxcar SP 29637 RTR

This HO gauge boxcar is built to go straight on the track. The "RTR" in the title means it's ready to run, with body, weight, couplers, wheels, and trucks included. It's factory painted and lettered in Southern Pacific Lines colors, with a brown truss-side wood boxcar body. The ready-to-run build makes it an easy choice; the missing original box is the main drawback.

What stands out from the listed details

  • Out-of-production appeal: This car is no longer in production, and it's described as a limited edition.
  • Ready to run: You don't have to assemble anything; it arrives as a complete car.
  • Classic proportions: The 40-foot truss side design gives it a distinct, older freight-car character.
  • Entry point: This is a straightforward way to add a recognizable boxcar to a consist.

Meaningful trade-offs

  • No box: The car does not include its original box. If you keep rolling stock in packaging, this could be a dealbreaker.
  • Used condition: It's used and graded C-7 Excellent, so it won't be mint.
  • Possible surface rust: Because of age, the wheel axles, car weight, and steel parts may show light surface rust. That's a normal sign of age, but worth checking before running it on expensive track.
  • Adult-focused: The age level is 17 years and up, so this isn't a toy for younger kids.

Bottom line

The MDC Roundhouse 1034 Southern Pacific 40' Truss Side Boxcar SP 29637 is a solid pick for HO modelers who want a boxcar at $11.95. It's full of old-school character. Accept that it lacks a box and may show some age-related rust, and you'll have a boxcar that fits right into an older freight fleet. If you need a factory-fresh, boxed example, this one isn't it-but if you're after a runner with classic appeal, it's worth a spot on your roster.
