Very cool video. Thank you. A few questions....I am guessing those hoppers were pushed up the hill with closed couplers which were not engaged?  Or were those rotary couplers? I guess what I am trying to figure out is if someone buys one of these tipples, will you have to start buying coalporters with rotary couplers? I think MTH stopped producing the rotary couplers(I think). 

Hi there. I work at a coal fired power plant that has one of the real thing.  Out in the 12" to the foot world, there are several different manufacturers of the railcars themselves, with differing dimensions.  The length is not standardized, which mean you can't guarantee you can dump cars without uncoupling.

Typically here we empty the first car in the cut, then push it through and uncouple it.  Then back up so the rotary coupler(s) of the next car is hanging out one end.  Dump the second car and push it out to the first one that got uncoupled.  Repeat until the string is completed.  I think we dump in 10 to 15 cars strings.  

May God Bless us all.
