Maunsell SECR N Class Mogul (NWR Tank Loco Rebuild)


The N Class of mixed traffic 2-6-0 locomotives was designed in 1914 by Richard Maunsell. Production of the first batch was delayed by the outbreak of the First World War. Assembly began towards the end of the war and the first locomotive, No. 810, emerged from Ashford Works for proving trials in July 1917. No. 810 was trialled for three years before another 15 locomotives (Nos. 811–825) were ordered in 1919. These were built between 1920 and 1923; their construction delayed by a backlog of repairs caused by the war.

The first batch of the N class proved successful in service, and the Ministry of Supply drew up a contract for a second batch to the same specification – to be built at the Royal Arsenal, Woolwich.  Building of the second batch went ahead to retain skilled labour at Woolwich, and by 1924, the prefabricated components stored at Woolwich formed 110 complete N class kits for purchase from the government.

Note: The above is true apart from me adding a fictional 10 loco ‘kits’ to include in my fictional universe. Info from wikipedia.

In 1924, the NWR, in desperate need of locomotives, purchased several of these ‘kits’ to assemble at Crovan’s Gate works. 3 of the locos were built as 2-6-2Ts for working commuter services, with 5 becoming tender locos.

All were named after important figures in Sudrian history. Sigrid of Arlesdale was the daughter of Ulf, who was one of Thorkell’s trusted lieutenants.

The Sigrid Saga calls Sigrid “… a lady wise and brave . . . more skilled with sword and bow than many a man . . . a worthy helpmate to her valiant lord . . .”. It goes on to describe how, following Orm’s death while defending Arlesburgh against Norman assault in 1094, Sigrid finally defeated the invaders by a brilliant rearguard action at Cas-ny-Hawin.

Sigrid, as a widow, ruled Arlesdale wisely and well for 20 years restoring the devastation wrought by the Normans, and building a church of stone in thanksgiving to God and St. Machan wherein she placed a memorial to her husband, Orm. Sigrid died, much mourned, in 1114

The Model

SIGRID is a static model and is made from a mixture of a Great British Locomotives N Class mixed with a cut and shut cab, bunker and tanks from a Hornby Fowler 4P 2-6-4T. The tanks were shortened, as was the bunker, which I also dropped in height. I wanted there to be a running theme of tank extensions in NWR locos, as with No.301.

The design was influenced by the Metropolitan Railway’s K Class 2-6-4T, themselves made from Woolwich Mogul ‘kits’.
