(Hoping this is in the right forum - apologies if it isn't!)
I was playing the excellent Hellfire game (www.railrover.co.uk) the other day, and I got the gen that a pretty big NB loco was out on a passenger working... but it set me thinking: it was shown as "37106 xit GD".
Now it might be just my memory, but I don't recall "xit" being "a thing" back then: I always thought that twin-tanked 37s (the "t") were ones where the boiler had been removed, rather than just isolated - because as I understand it, the former boiler water tank was converted into the additional fuel tank. So shouldn't the loco have been "xot" rather than "xit"?
Does anybody know whether that is gibber or I'm right? Were there in fact twin-tanked 37s which retained their isolated boiler?
Any thoughts would be warmly welcomed!
