Reading about the firing up of the engine from a 'Baby Deltic' and the possibillty of using bits from other English Electric diesels could recreate one, is it possible that that some diesels which are extinct could be reserected in the same light as some steam types? (eg. A1, Grange, Brighton Alantic...). One example of a diesel which is missed (although not for its unreliability) is the North British class 22 diesel hydraulic. How could such a new engine or replica be built? My guess would be to track down the correct MAN engine and transmissions from, I guess, Germany and build a new cassis and stretched skin panels around it. Is this possible? Spear engines have been found for the other preserved diesel-hydraulics One advantage over steam new rebuilds is if the right engines, etc. can be found, it could be cheaper then to build a diesel rather then a steam engine. However on the other hand, fund raising for such a venture could be difficult because it would as interesting outside of diesel enthusiasts. However it would plug a gap in Western Region post-steam era, as most diesels associated with the West County are the North British’s replacements. Penny for your thoughts?
