Reply to "Fast freights or slow freight"

I set the max speed on my engines equipped with MTH PS at 70MPH. The speeds of each train depends on the situation. Most freight trains run around 50MPH once assembled and stretched out, out on the mainline. I just settled on that speed and our grandson did too. He came up with 45 to 50 on his own. I think it's a good speed for watching long freights go by.
