Though engines started getting bigger early in the 20th century, no one could foresee the monsters that were in regular service by the 1940s. These locos required equally large servicing areas, so some roads simply added and extended a few roundhouse stalls to handle them. This conversion kit adds three matching stalls to the Modern Roundhouse (933-2900, sold separately). With additional kits, you can expand the basic building to any size your railroad requires. Engines up to 125' fit easily inside, and parts to build a single 145' long stall are included - big enough to hold a Big Boy.
