Models

In October 2015, the British model railway brand Hornby Railways announced that it would make a OO gauge model of the Pecket W4.

In February 2016, Hornby Railways also discussed how the first batch of liveries were 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. Now Hornby are releasing a model of the preserved locomotive Bear that is at the S&KLR in a questionable condition.
