MDC / PIKO G “Mainline Series” Rolling Stock

Last Updated: 25 April 2022


MDC / PIKO G “Mainline Series” History

PIKO currently offers a range of rolling stock called the “Mainline Series”. The Mainline Series range includes American style ore cars, box cars, reefers, two-bay hoppers and cabooses in various paint schemes. Some of the cars are available in a (fictive) German DB paint scheme as well.

The molds for these models are not developed by PIKO. The original company making these molds was called MDC (“Model Die Casting”) / Roundhouse. MDC sold the molds to a company called “Mainline America”. It’s unclear whether Mainline America actually produced new models with them. If they made any, it would be in very low quantities.

The MDC molds eventually ended up at PIKO, and all ex-MDC models are sold under the “Mainline Series” label.

Offered in PIKO’s G scale range are the following cars:

  • Ore Car
  • Two-Bay Hopper
    • Offset-Side
    • Rib-Side
    • Covered
  • 40′ Boxcar
  • 40′ Reefer
  • Wood Caboose

All cars (except the caboose) are considered to be (close to) 1:32 scale, and are therefore quite popular with 1 scale enthusiasts. Compared to “G” scale cars, they look rather small. The wood caboose is an exception, and is believed to be 1:24 scale.

PIKO will continue to offer new paint schemes in the Mainline Series, but completely new designs – for example the 2-6-0 Moguls and Camelbacks – are part of their “regular” G scale product range.
