Once you go to purple boxes, you won't want yellow boxes any more.
We started with RK in diesel and steam. Then we got a taste of Premier diesel. So we said, OK Premier diesel but RK steam. That then changed to all premier... Diesel, Steam, Freight and Passenger.
By the way the Premier S-2 Unit Measures:12" x 2 3/4" x 3 3/4" - Operates On O-31 Curves
It looks like MTH did not make the S-2 in RK, but the SW1500 looks similar.
The SW1500 Unit Measures: 11 3/4” x 2 1/2” x 4” and Operates On O-27 Curves
Your sizes look close enough that it would not look out of place.
Good Luck with your decision (Get It).

I run both on my layout at the same time. I see no difference unless you are running Premier Steam along side RailKing then you will notice the difference. LikeRon stated the purple boxes can be addicting!
