Thank you everyone.
Yes, Steel Mills were not a walk in the park to work in.
The flatcar will be used for any job that's required but slabs go to the top of the list.
I already have made ingot buggies there is nothing wrong with moving some empty ingots or even the moulds from one place to another in fact I like this car so much I am going to do another one.
The load on the car is made for a 40 foot gondola which is why it has a sturdy base and you don't see it in a Gon. My back is holding up for now.
