The Class 121 is a true icon of the Western Region. Built by the Pressed Steel Company in 1960, these single-car units were designed for the quietest corners of the network, but their rugged reliability kept them in service for over 50 years. From the rural idylls of the 1960s to the final Chiltern Railways "heritage" shuttles in 2017, the "121" is a legendary piece of British engineering that feels at home in almost any era.

Capturing the "open" feel of a Bubble Car is all about the glazing. Our Class 121 features expansive, flush-fitted windows that showcase a fully detailed interior—including authentic seating, internal partitions, and high-fidelity driver's cabs. We have meticulously recreated the specific roof-mounted exhaust pipes and underframe cooling fins that define this class, ensuring a model that looks as good from the side as it does from the cab front.
