I'm kind of hoping to be able to replace MPC era Mghty Sound of Steam Southern Crescent and Chicago Alton Locomotives with LionChief +. I know one of the first LC rtr sets was the Broadway Limited I believe that was one of first the MSoS sets too. Maybe they'll come out with a LC Milwaukee Special rtr Passenger set.
Are there any other MPC era trains you'd like to replace with LionChief?
