Something will have to replace the mk1 eventually.
And mk2 and mk3 aren't that much newer in the scheme of things.
It occurs to me that the design and manufacturing could perhaps be separated.
Interested parties could work together to create a new standard reference design
for a suitable passenger coach, that met all of the various legal and
technical requirements for the basic vehicle.
Maybe with different options for various parts like internal seating and layout.
(Or even low speed preserved vs main line options)
Then it could be built in small numbers by existing preserved railway workshops in much the same
way as steam locomotives and existing coaches get built or maintained.
Each group could raise money, as they go, for one extra coach at a time,
rather easier than a single big order (which looks next to impossible)
Have I just proposed an equivalent of the IET for preserved railways?
