Happily, 37403 is still in service. The last time I saw the loco was on 23/09/22, at Grosmont sheds during the North Yorkshire Moors Railway annual steam gala.
I've rode behind 37403 a few times on the line, though mostly from Grosmont to Whitby.
For those interested in the loco in front of the 37, that is Class 47 47077 North Star.
(Note: I know I've posted the photo on here before but I thought I'd share it again after seeing the other photo of the same loco)
