Allan ‘did not design Crewe-type’ engines: there’s more to the story

I enjoyed reading issue 250 of Heritage Railway and was delighted to find an interesting article by Brian Sharpe regarding 1840s locomotive engineers.

As a professional railway historian studying and writing about the period 1830-50, it is always nice to see something – anything – from the earlier 19th century. However, I feel I need to note that neither Francis Trevithick nor Alexander Allan had any involvement with the design of the ‘Crewe’ type and furthermore, that name is a misnomer.

The locomotive has had its cab removed so that it appears as it did in the early 1870s. ROBIN JONES

Thanks to very sharp curves leading into Warrington Junction on the Liverpool & Manchester, the GJR suffered from a series of crank-axle failures on their 2-2-2 Patentee type locomotives.

The situation had become so bad after only two years of operation that Joseph Locke was investigating building a standard locomotive and means of reducing the frequency of axle breakages.

A year later the GJR board ordered Buddicom to report on the matter and how best to tackle the issue of crank-axle failure.
