I would like to recommend to DTG the class 442 "Plastic Pigs" They used to run on "Network South East" "South West Trains" "Gatwick Express" & "South Western Railway" These trains are Mk3 Derived trains powered by the 3rd rail. These trains have been the backbone for commuters until 2021 (SWR) These trains run with 5 coaches and were sadly withdrawn from service with only 1 Driving Trailer saved. These are some great trains in my opinion and it would be nice to see in TSW
