Hattons Originals O Gauge LNER Class A4 4-6-2 - Product Info

Wednesday, November 24 2021

Hattons, in partnership with Heljan, have produced a range of newly tooled LNER Class A4 4-6-2 locomotives in O gauge. A number of variations cover the lifespan of one the world's most iconic steam locomotives in a selection of LNER and British Railways colour schemes. We have also produced unnumbered variations, which enables you to run exactly the locomotive you wish to, with accurate tooling variations ensuring they are as prototypical as possible.

Cabside Handrails:

Our models of the Class A4 are supplied without vertical cabside handrails, due to an oversight in the design process. This was discovered too late in the development to amend the models, and we have been unable to source suitable parts for customers to fit these themselves. We apologise for any disappointment this may cause but we are unable to offer suitable parts at this time.
