As I look at those flat cars I now just noticed they are not just a run of the mill flat car,they were made to haul heavy loads with 3 axle trucks.When I first looked at the picture I thought they were on a standard flat car.Also did not take into account the time erra,and rail cars were over all not as well built
as most are now and you could not just load a tank on any flat car as you most likely could on a lot of modern cars we have today.It was also mabe that those cars were built specificaly to haul tanks and that they were allreay wider than a standard car and a few additional inches was a major factor.
