Darin Long, one of the directors of the Great Falls Model Railroad Club in Auburn puts a train back on track Friday morning during the club’s annual ExTRAINaganza. The club toyed with not opening again this year because of the uptick in COVID-19 cases but most members were on board. They are rolling along with another successful year that concludes this weekend. Tickets are $5 and can be purchased at the door from 10 a.m.-4 p.m. Saturday and Sunday.  Russ Dillingham/Sun Journal
