RE: Turning without a differential (how does the train do it?)

in #steemstem7 years ago

How more could you have explained that. I see train at least 3 times a day. But i never knew some of these points you explained about them.. Especially the one of The shape of the wheels.. The inner one and the outer one. The way they are fitted on the track. I will try and notice one tomorrow.
I am glad i learnt something new.
