I believe there are two further additions to ranks of the preserved road-railers
Firstly a trackmobile PQ364 at the Keith & Dufftown Railway:
Secondly, another trackmobile at Mangapp's Railway Museum:

Perhaps these are beyond the scope of this website, which is why they aren't already added?
Whilst they do have road wheels, rail wheels and are generally yellow, we have decided that these are beyond the scope of the site.
(Cue Ben complaining about that JCB FastTrac shunter thing that is listed :)
Indeed. There is one at Colne Valley too. But not for this website :-)
Not forgetting a further one at the East Lancs Railway
