About Us
Parts4Marx is the exclusive online retailer for The Robert Grossman Co.
We are a small family-run business dedicated to serving the Marx train collecting community.
All parts manufactured by The Robert Grossman Co. are made right here in the USA. Most orders can be shipped within 72 hours, but some parts are hand made by train enthusiasts and quantities can be limited. Your order may be delayed 8-10 business days if it includes a hand-built part that’s made to order.
For over 30 years, Robert Grossman has passionately supported Marx collectors by manufacturing reproduction parts and servicing salvage parts for Marx trains. The Robert Grossman catalog launched in 1997 and online sales began in 2002. He officially retired in fall of 2022. Parts4Marx is honored to continue his legacy, and that of his predecessor, Paul Gailey.
