By cutting a section out of the floor and inserting  the base plate, it can be fitted to other ready to run and kit built carriages.

SOUTHERN PRIDE kits and the HORNBY reissued B.R. MkI stock are of very similar construction and require a little more effort to fit the base plate. In both cases the bogie centres are too far apart and   

Listed here is some of the  stock  that  the Close Coupling System will fit to.  It only takes a little imagination. If it is not listed, it does not mean it will not fit, but simply that I have not had one to fit it to.

HORNBY. LMS, SR, GWR, LNER carriages with the common 57ft underframe, the operating mail coach and both types of clorestory coach.

Note the modified position of the drop arm and coupling box.

This method would also be used for Southern EMU’s.
