Ivatt GNR tender identification
Posted: Mon Feb 28, 2011 6:25 am
I am trying to identify the tenders used for various GNR locos (LNER D2, J6, J1 etc).
If I have understood what I am looking at, I cannot use the wheelbase as an identifier (earlier = 6'6" + 6'6"; later 6'10" + 6'2"). The definitive diagnostic would be the shape of the coal hopper (horse shoe vs self-trimming).
The only thing I can see helping here is the location of the water-filler overflow vents (small conical mushrooms) on those tenders that have scoops fitted. The horseshoe tenders have these set further to the rear, than the self trimmers, correct?
Any help on:
(1) How to distinguish these tenders
(2) The chronology of GNR tender orders
(3) relating A and B to the above.
(4) Sources (almost certainly within GNRS and currently unpublished)?
