I have just realised that I still haven't been on a Class 91 hauled train with Mk4 stock. I remember when I first moved to Derbyshire in 1989, I would travel back to South Wales every weekend and go past the Metropolitan Cammell (?) Works in Birmingham and see the shiny new coaches in the sidings ready to go into service. I am also still yet to travel on a Pendolino. As for Azumas, people will be sentimental about them by the time I get to go on one. 2 1 Link to post Share on other sites More sharing options...

Current US diesel locos are typically 15' 6" or so high & 10' 6" wide. (The UP Big Boy steam locos were 16' 2½" tall and 11' 0" wide) Double stacks and Autoracks are considerably taller than that, typically triple deck Autoracks are 19' 11" - 20' 2" high & double stacks between 18' 2" & 20' 2" 3 Link to post Share on other sites More sharing options...

Looking at the excellent photo again in a bit more detail, I see a couple of interesting things (to me at least). First, the signal facing the camera is a LQ "slotted" arm, and secondly, the two tall telegraph poles are outside the railway boundary carrying (assumed) GPO services over the railway. Probably the most direct route, and the GPO weren't going to let a railway line get in their way! 1 Link to post Share on other sites More sharing options...

The large major axis of oval buffers leaves them less prone to buffer locking without requiring the mass of round buffers of that diameter.

Unless of course you have eyewatering vertical curvature. But if you're trying to avoid buffer locking in the vertical plane, it's probably a better solution in the long run to find the Civil Engineer and beat them repeatedly with a copy of the design standards until they fix the alignment. 4 Link to post Share on other sites More sharing options...

Hesperus Posted March 10, 2021 Share Posted March 10, 2021 So assuming the track isn't that wonky in many places why do so many engines have round buffers? Link to post Share on other sites More sharing options...
LMS2968 Posted March 10, 2021 Share Posted March 10, 2021 (edited) Much depends on the throw-over on curves: the longer the engine beyond the fixed wheelbase, the greater the misalignment of buffers and the greater the risk of buffer locking. It isn't a hard and fast rule tough: the Britannias got round buffers while 71000 had oval, although the overhang was near enough the same in both cases.

Oval buffers need some means to prevent rotation - so they're more complex and cost more pennies than roundy roundy ones ! 2 1 1 1 Link to post Share on other sites More sharing options...
