Romney, Hythe and Dymchurch Railway (RH&DR) locomotive No.7 Typhoon is a 4-6-2 steam locomotive built by Davey Paxman & Co. in 1926-1927 and delivered on the 19th of May that year . It was one of the last two pacific locomotives based on the original locomotives ordered by Captain Howey in 1924. The design was based on the LNER A1 class which Flying Scotsman belongs to. No.7 Typhoon and No.8 Hurricane differed slightly from the RH&DR's earlier pacific locomotives due to the addition of a third cylinder. This change was done as part of an experiment by the railway's then-owner, Captain Howey, who was craving more strength and speed form his miniature locomotives. The third cylinder was ultimately found to be more expensive and less reliable. Because of this, the railway converted both Typhoon and Hurricane into two-cylinder machines in 1935-36.

As part of a publicity stunt, there was a detour during delivery to the Romney, Hythe, and Dymchurch Railway in April of 1927. Typhoon was taken to LNER's Kings Cross Top Shed where it was staged next to its full-sized sibling, Flying Scotsman. The image was recreated for postcards and promotional material for the miniature railway, but was eventually forgotten. It wasn't until Flying Scotsman's return to operation in 2017 and the preparations for the book to celebrate the RH&DR's 90th Anniversary that the 1927 photo resurfaced. When Scotsman's 2017 tour plans were finalized, staff at the Bluebell Railway reached out to their RH&DR counterparts and plans were made to reunite the two locomotives for the first time in 90 years. Both locomotives were displayed/based at the railway for the week of Flying Scotsman's visit.
