Arguably the most useful of first generation diesel multiple units (DMUs), the
Class 121 ‘Bubble Car’ comes to Train Simulator in distinctive BR Blue livery.

The unusual single-car units were manufactured by Pressed Steel Company from
1960 onwards and introduced by British Rail for use mainly on the Western
Region and around London on suburban and branch line duties. Their distinctive
exhaust pipes designed to fit around a large four-digit headcode indicator box
made these units fondly regarded by rail fans for their unpretentious
appearance and old-fashioned interior and performance characteristics.

The ‘Bubble Cars’ became familiar for running Network SouthEast services and
upon privatisation of British Rail, the fleet was operated by only one
passenger company – Silverlink – with several more units in departmental
duties with Railtrack. Today, two Class 121 models remain in revenue
generating service with Chiltern Railways, representing the last chance to
ride on 1960s slam-door stock on the main line in the UK and signifying a
remarkably long life for these fans’ favourite. Five motor cars also remain in
preservation across heritage railways in the UK.
