I have the intent on doing such on my RR but it is still shut down for renos. (meteor named Home Depot slammed into my main dominos and leveled the industrial park/mainline.

I think you will have fun Pete, as long as everyone intends to have fun and not nitpick things to death for operational realism.

(nothing worse than being criticized for ones choice in track arrangement for yard lead ,etc as it wasn't proto correct. Not everyone has room for accurate sidings,etc. don't know about other people but I don't have 30 ft to devote to a corrctly arranged yard.
I've heard of people using deck of modified playing cards, shuffling and picking out several to determine cut of cars to sort,etc. Others have cards for eerytie they pass hotbox detector where they draw a card for ever train passing thru hotbox. card could say proceed, stop for inspection, or stop and you have a bad car to cut loose. Maybe try starting with train orders and not worry about schedules, as everyone may be slower running their train as getting use to operations, then wing it if you have a train meet. Once you guys have the hang of it, then put schedules in place. It might be a little too intimidating starting from scratch and trying to adhere to schedules as well.
Calls for a beer call to look at ones layout to come up with ideas for consist cards, train orders,etc.
