Talk:Train wheel

Road-rail vechicles.
you might want to mention that the rail wheels on a road-rail vehicle do not support the weight of the vehicle. The vehicle (usually a light truck) still rides on its pneumatic tires. The rail wheels only serve to guide it, so that the pneumatic tires will stay centered on top of the rails. 75.149.30.179 (talk) 14:45, 18 December 2020 (UTC)

 * Yes, I've seen an excavator in action on track where the road wheels appeared to be going backwards; the reason is that the powered road wheels were in contact with the unpowered rail wheels and were turning the rail wheels to effect motion.  For this to work, the road wheels necessarily have to be raised above the rails. FreeFlow99 (talk) 12:12, 29 June 2021 (UTC)

Add info about why guide wheels are needed?
I was reading this article and it seems like these type of trains need extra guidance but i was left wondering why. This heading now contains few information and leaves me wanting more Pingiun (talk) 13:08, 9 January 2023 (UTC)
 * Are you referring to the section Train wheel, or somewhere else? -- Red rose64 &#x1f339; (talk) 13:24, 9 January 2023 (UTC)
