Model Rail Class 11 and Class 12

Model Rail has joined forces with Heljan to bring you the LMS 350hp diesel shunter, later to become the Class 11, and the later Southern Regon Class 12s

Model Rail Heljan Class 11s
You could be forgiven for mistaking this machine for BR's superlative Class 08 but this is where the "gronk" story starts. The differences were small (wheel diameter and cab) but what we have here is the final evolution of the LMS pre-war diesel shunter development.

The War Department ordered the first 20 (but only took delivery of 14), the LMS took the remaining 6 and BR built 71 between 1948 and 1952 when Class 08 production started. Even the Western Region took delivery of six machines that were virtually identical to the LMS design, and English Electric built them for industry too. Eight Class 11s survive, plus one ex-WD and one built new for ICI.

15211 -  15236 emerged from Ashford between 1949 - 1952 and were virtually identical to the LMS design. We will include key differences - Bulleid-Firth-Brown wheels and the extra lamp iron/marker lights - but please be aware that limitations to the tooling may mean that it's not possible to include some smaller detail differences (also applicable to the Western Region machines).

Boasting an impressive technical specification - plus a wealth of detail - the models are supplied in DCC ready format, with a Next18 DCC socket and pre-installed speaker.

The models also feature a super-smooth mechanism, with gearing optimised for slow-speed running - perfect for these venerable shunting locomotives. 

As well as working exterior lamps (on certain models only to match the prototypes), the cab interiors can also be illuminated by activating a hidden switch using the supplied magnetic ‘wand’. DCC users have even more control over the lighting functions.

We have 15 Class 11 versions to choose from, encompassing LMS, War Department and British Railways liveries, along with schemes depicting some of the Class 11s that enjoyed second careers in industry. There’s also a mix of pristine and weathered options available. 

As well as different paint schemes, the models also feature prototype specific details. This is thanks to our investment in extra tooling, allowing for several detail differences to be incorporated, including alternative nose end detail, three different marker light arrangements, handrail placement, air horns or whistles and several other small - but vital - differences between batches.

Note: images are of all pre-production/livery samples and subject to alteration. 

The Southern Region Class 12s will follow later.

The models are shown below, each is limited to 300 pieces.

- The Class 11s arrived in early February 2024 and are now in stock and available to order.

Heljan Class 12

We’re also working on five versions of the similar BR Southern Region Class 12, complete with Bulleid-Firth-Brown wheels. Like the Class 11s, we’ve designed the tooling to allow for original and later versions to be replicated, with and without electric head/tail lamps.
