wwrsimon Posted September 10, 2023 Share Posted September 10, 2023 Hello everyone Apologies if this is a daft question, but why do these two GBRf Class 92 locos seem to have different ride heights? https://www.flickr.com/photos/153305438@N06/51369027254/ The orange/blue example appears to be sitting lower compared to the grey one. Thanks Simon Link to post Share on other sites More sharing options...
RMweb Premium iands Posted September 10, 2023 RMweb Premium Share Posted September 10, 2023 The one on the right appears to have worn tyres, thus it is sitting a bit lower than the one on the left (which doesn't have worn tyres). 2 1 Link to post Share on other sites More sharing options...
Wickham Green too Posted September 10, 2023 Share Posted September 10, 2023 Could ( also ) be a slight dip in the track. 1 Link to post Share on other sites More sharing options...

Good spot, thanks. The wheels on the orange/blue loco defintely look a lot more worn than the ones on the grey one! Simon 1 Link to post Share on other sites More sharing options...

If you look carefully, the gap between the top of the bogie step and the bottom of the body is smaller on the loco on the right. It could be something like it's longer out of works and the springs are more worn than the other loco. The one on the left has definitely seen works attention recently - look at the new axle end covers and shoe beams. Link to post Share on other sites More sharing options...

The orange one just seemed to be a bit more 'used' and in need of some TLC. It looks a little sad compared to its mate... Simon Link to post Share on other sites More sharing options...
AMJ Posted September 12, 2023 Share Posted September 12, 2023 There is not much height change with worn tyres as that would account for about 3" maximum height difference. I'd agree that it is most probably spring settings causing the elevation. Link to post Share on other sites More sharing options...
jim.snowdon Posted September 12, 2023 Share Posted September 12, 2023 The axleboxes on the right hand loco are visibly nearer to rail level compared to the other loco, which would indicate a smaller wheel diameter. Everything else appears similar in terms of gaps which would suggest that there are no significant issues with the suspension. 1 Link to post Share on other sites More sharing options...
Wickham Green too Posted September 12, 2023 Share Posted September 12, 2023 Just twigged what it is - apart from worn wheels and a dip in the track .......... it's that springy thing on top that's pushing the orange one down ! 🙃 4 Link to post Share on other sites More sharing options...
bécasse Posted September 13, 2023 Share Posted September 13, 2023 The middle wheel set of the visible bogie of the left hand loco looks as if it is mounted on a skid. If it is that would account for the difference. Link to post Share on other sites More sharing options...

Thanks, interesting that today's railway has to use something so unsophisticated and, dare one say it, cheap. Link to post Share on other sites More sharing options...
Wickham Green too Posted September 13, 2023 Share Posted September 13, 2023 No idea whether they use anything more sophisticated nowadays - but this was the late 70's cheapskate skid ! 25.047, Craven Arms : 19/12/79 ( VERY late 70's ) 1 Link to post Share on other sites More sharing options...
