Milwaukee Steam Power
Northern Pacific Steam Power
SP&S Steam Power
Steam that's never been offered in O scale.
I love Steam but I see that these could be hot sellers.
FM Erie Built AB units. Those would go great with the GGD Hiawatha passenger set.
Amtrak Cascades Talgo Set would be cool. Never offered in O scale or any other scale.
A better model of the Amtrak GE P42 than MTH with more prototypical detailing.
ALCO Century Series. C636's which have never been done on O scale.
