Yes, trains CAN get flat tyres, or more correctly, flat spots on tyres. They have a steel "tyre" pressed onto a cast wheel and can get wear from braking or, on a driven axle, from accelerating too hard! (that spins the wheels) The wheels can also crack, I can just remember when I was a kid, seeing a railway man walk alongside a train, hitting each wheels with a metal hammer on a long handle, listening for the tell-tale sound of a cracked wheel.
I like the 1957/58 Chevrolet Viking, or I think they may have had another name for such a heavy duty model. It is all blinged up with whitewalls and other things no self respecting driver would want but all in the name of advertising.
I have my shoulder to the wheel,
my nose to the grindstone,
I've put my best foot forward,
I've put my back into it,
I'm gritting my teeth,
Second shot, definitely photo shopped. Both wheels on one solid axle, only one worn out????
no catastrophic failure of the wheel most probably due to an undetected crack in the wheel itself. For some reason railway wheels tend to fatigue crack from the inside.
They used to detect the cracks by hitting the when with a hammer and listening to the sound. a ring meant everything was ok. A dull thud meant that the effected equipment was taken off the train and sent to the nearest workshop/bogie exchange area for the bogie to be replaced and the whole bogie was sent off for reconditioning.
Now everything is privatised I am not sure it's done anymore. They probably have a method but it doesn't seem to be performed as frequently as before, I have seen some places overseas ultrasound them every service but that's not as frequent as a daily tap with a hammer. Maybe better materials technology means it doesn't need to be done as often?
Having lived through a pandemic I now understand all the painting of fat people on couches!
Bruce, if both wheels are fixed and on the same axle and turning at the same rate, as all train wheels do, how come the wheel on the opposite side is not worn down the same? As Pauline says, "Please explain?"
