The elaborate Lionel train layout at the Henry Sheldon Museum in Middlebury, Vermont is an annual tradition, delighting all ages. The assemblage stands three levels high, with tracks running Lionel O gauge trains, Lionel 027 gauge trains, and an upper track running HO trains. The layout includes a backdrop of the Green Mountains painted by local artist Gayl Braisted, an operating gondola ski lift, skiers, snowboarders, and rock climbers, and bicyclists.
