Jack and The Pack or Jack and the Sodor Construction Company was a mini-series devised by Phil Fehrle to be a spin-off of Thomas the Tank Engine and Friends. The plan was soon scrapped when HiT Entertainment took over because it conflicted with their other construction-based series, "Bob the Builder". Twenty-six episodes were planned, but only eleven were filmed. The characters only appeared in two sixth season episodes, Jack Jumps In and A Friend in Need. In 2008 a 2 disc DVD, On Site With Thomas/Thomas's Trusty Friends, was released. Since then, The Pack has made appearances in The Great Discovery and the twelfth season episode, Percy And The Bandstand. Jack appearance in CGI in the 2013 special, King of the Railway, Alfie, Oliver, Max and Monty returned in the 2015 special Sodor's Legend of the Lost Treasure

For this series, large-scale models of Thomas and Percy were built. Two of these models are now on display at the Japanese Thomas Town. Headwriter Andrew Brenner stated on his CV that he has worked on this series since 2009. This may be an indication that the series, or at least its characters, will make a comeback. Jack having returned in King of the Railway also supports this speculation.
