The Peckett W4 class is a class of 0-4-0 ST steam locomotives built by Peckett and Sons at the Atlas Works factory in Bristol, England from 1885 to 1906. 140 Peckett W4 locomotives were built in total,[1] and they were part of a family of six W-class locomotive engines (W2 through W7), which featured cylinders 14inches in diameter. The W4 class has a piston stroke of 200NaN0, driving wheels with a diameter of 3feet and a wheelbase of 5feet.
The more notable Peckett and Sons customers (and the number of locomotives they purchased) included Manchester Ship Canal (3), Ebbw Vale Steelworks (2), and Huntley and Palmers (1).
In October 2015, the British model railway brand Hornby Railways announced that it would make a OO gauge model of the Pecket W4.[2]
In February 2016, Hornby also discussed how the first batch of liveries was painted: Dodo (563 of 1893) was painted the default light green used by Peckett and Sons (unless the customer specified otherwise). No. 11 of the Manchester Ship Canal (654 of 1897) was painted a dark green, while Huntley and Palmer's 'D' (832 of 1900) is painted in that company's lined blue livery.[3] Hornby has since released a model of No. 614 Bear, preserved at the S&KLR.
