I think GBRF has probably earmarked all of the remaining 73's for retrofit with the new engines and bin the 20's.Vertically squashed battery 73? A bit like the Merseyrail Sandite unit once was, being formed of two Class 501 trailers with a 73 in the middle?
brush traction seems to have done a sterling job and made the 73's something really quite useable now.
the old class 20's were great because they had low RA and small wheelbase,they could go anywhere,but their days are numbered now.
there are still plenty of rural freight routes and local branch lines where a 66 is really a complete waste of resources.
pair of 20's, good in tandem but fuel hungry,useless individually
class 25...would have been fantastic with a better more powerful engine
class 31..some RA issues and underpowered/unreliable
class 33...not bad at all for a light-ish duty mixed load engine
class 37...good workhorse,but not so flexible on routes with sharp bends as co-co.can't hack it for really heavy duty freight(cue class 66)
class 47..STILL damn good multi purpose unit.
in the retrofitted 73 ,brush have now got a class 20/class 37 hybrid.
