Thanks Nick and Quickj. I picked up 2 Bing O gauge live steam locos 2 weeks ago, will post pics soon. I plan to run these on the Highline track at the St Croix RR. Nick, see you soon at Iowa Heritage steam school. I have a RR buddy who is also attending the steam school, and may attend the August show in an effort to get his hours in for the MN license. He has a 1/2 scale Alchin traction engine of recent construction.
