The last two times we've had city trains the set numbers went station-passenger-cargo, so IF that continues and 60197 is a passenger train then 60198 would be a cargo train and 60196 would be a station. .
7937/60050 Stations
7938/60051 Passenger Trains
7939/60052 Cargo Trains
My thoughts: Given that City trains really must appeal to KFOL to sell and since newer sets have been much sleeker/realistic, I don't know if we'll ever see a City steam engine.. but what's left for them to do? I'm not a real life train fan, so not sure what's out there. Maybe I'm wrong and kids do like steam engines, but I can't see one in their marketing for modern cities.
They've done the high speed passenger train, so I'm hoping for a commuter or subway shaped train of some sort.
For the cargo side, looking at 60098 kinda being a rehash of 7939's shape and 60052 being the last cargo train - maybe we'll get a green remake of 3677? Again, not sure what other train engine types there are for inspiration.
I wonder if they'll start making trains like Police/Fire - rehash the old ones once they figure out what sells best.
HE was $130, but wasn't a city set that included PF.
