There is also a pic of all the locos that will come with the route.

"Three locomotives are included: an SD40-2 which is a modified RS.com locomotive repainted in Pan Am Railways livery; a "restored" Boston & Maine E7 using a shell by Dick Cowen; and a set of three GP40s in Maine Central, Guilford and Pan Am liveries."
