The Class 121 single-car Diesel Multiple Unit (DMU) is Bachmann Branchline’s flagship First Generation multiple unit, equalled only by its 3-car Class 117 stablemate. Employing cutting edge technology, these high fidelity models boast a wealth of detail and era-specific options to depict specific railcars at various points during their working careers which, for some, extended towards 60 years in service. Returning to the Branchline range in a selection of new liveries, these iconic suburban DMUs will make a fine addition to any model railway set in the steam-diesel transition period onwards.
Capturing the look and character of the prototype, this Class 121 is adorned with many separate detail components whilst underneath the engine, drive gear and auxiliary equipment is all depicted faithfully. It may be hard to believe, but within these components and integrated into the underframe is hidden the drive mechanism, which is totally invisible with no intrusion into the interior of the model. Talking of the interior and the fine detail extends inside the model too, complete with prototypical decoration. The livery application is executed to a high standard both inside and out, using accurate colours and authentic fonts, typefaces and logos to stunning effect.
Driven by the low profile mechanism, the technology continues with the lighting suite which includes directional lights, interior cab and passenger saloon lights, and Illuminated headcode boxes and destination blinds, all of which can be enjoyed by analogue users – controlled with the under-chassis switches – or via dedicated functions on DCC. With a Plux22 DCC decoder socket and pre-fitted speaker, these models are ready for sound or why not opt for a SOUND FITTED which provides authentic sound effects on both DCC and Analogue Control straight out of the box!
