1000
The 1508 and 1507 lead a southbound passenger train through Denali Park in 1982. They are a matched pair of F's both by their numbers and their paint scheme. The nose of the 1508 is pretty worn and scarred, but not to worry. Next season it will be sporting a fresh coat of blue and yellow paint. The 1507 will not be as lucky and will head to retirement in 1985 still in black and yellow along with sisters 1505 and 1504.
