some of these pictures make it look like a small machine....very small machine, with big handles & knobs. just think of all the parts to a train and them each being made in batches and then assembled...lots of very heavy parts. and presision made...or else if the wheels were off in dia it would just go in circles like nascar.

now wouldent that be a sight. nastrain.

Yup! Those wheels are for the shunt engines that are being assembled there. You can see a couple of sets on their axles in the upper left of the pic and two locomotives upper right.

It looks like he is blowing compressed air at it. Does anybody know why?

I'm not sure in this instant, but I do know that to make toughened glass they heat it and quickly cool the surface which makes the outside shrink causing a tension In the plate, which is why, if you try to cut toughened glass it will shatter because you've released the tension in a local area.

Unfortunately, that would be a Chinese man working there... I found this in regard to glass production.

"China is the biggest flat glass producer in the world. In 2013, the total flat glass production in China reached 780 million containers, according to an industry report."
