Notch One?
More like notch 3 give and release 15 pounds then crank her up to 5 and 6 put in another 35 pounds, crank her down to notch 2, release brakes tug at a good and very quick 8 throttle down and put more pressure.
Sort of a tug, stop, tug effect.
Still wouldn't work though.
Highly illogical.

So it is impossible to yank a steam engine and ten flat cars out, this is a sad situation to be in, I wonder if that tunnel was inspected to be on the safe side but I highly doubt it!
