Well, I'm grateful that Lionel is showing some love to the GM&O. Mr Wolf has shown much over the years, but Lionel, very little. My only sure purchases from this catalogue are the GM&O wood chip hopper and TOFC trailer 2-pack.
The Southern is always welcome - and tempting - my home town (Mobile) was served by 4 class 1's back in the day; GM&O, Frisco, L&N - and Southern. (Also, Frisco could use some steam love, for sure.)
How about some of those lanky, green SOU Ps-2 Pacifics? Not everything - or every layout - needs a big Ps-4.
