The new 'Odin'; a model of the replica locomotive built in Denmark in 2018. 'Odin was the first locomotive in Denmark, in 1846, and the replica was built at Roskilde, Denmark, by the Danish Railway Museum to designs researched by Dr Michael Bailey and John Glitheroe in UK. Odin is very similar to other Sharp Roberts locomotives built for many British railways, including the LNWR and Midland, and is representative of the 'Sharpie' type in general.

The model is built to 10mm / ft scale as a one piece print (excluding certain fittings and wheels) in SLS (Selective Laser Sintered) nylon, printed by Shapeways. The design was made in Turbocad v.16 and, while right on the limits of capability for the software, does include every external detail shown in the Bailey / Glitheroe drawings. Wheels are also SLS printed, to G1MRA standard dimensions. Power is provided by a tender mounted ABC helical gearbox and Maxcon coreless motor with chain transmission and running from a single 3.7v 1200 mAh Lipo, similar to a cell phone battery. Smoke effect is provided by an ultrasonic transducer in the smokebox, atomising tap water.

I would also have been running the LNWR Stephenson 'Long Boiler' No. 153, built in 1847 as a direct development of the famous 'Great A' gauge-war engine. Long Boiler locomotives enjoyed a brief ascendancy on the LNWR after Edward Bury's departure and Stephenson's return, and handled most express services until about 1855. A type almost forgotten today, they are often confused with the Crampton type (which had the driving axle behind the firebox) and had the advantage of better thermal efficiency through the greater surface area of the tubes. They also fitted on the very short turntables of the time. However, they had a reputation for instability at speed which, although hotly disputed by Stephenson, led to one of them (the wonderfully named 'The White Horse of Kent') turning over on the Eastern Counties railway.

Like 'Odin', No. 153 is a one piece print in SLS nylon with tender drive. The picture shows the locomotive and train of representative 1840's stock at the G1MRA Midland Group Bulkington meeting in February 2020.
