Bradley Junction (Cambria Co.)-Heilwood (Indiana Co.)

Can someone explain the route an RPO postcard marked 'Bradley Junction-Heilwood' would have taken in 1907? There is also the number 'T773' in the postmark. Any help would be appreciated.

Bradley. Jct->Cherry Tree->Wandin Jct.->Heilwood

Interesting in that Heilwood is still listed as Possum Glory (its original name) in the January 1907 Official Guide on both the PRR and NYC listings. The PRR listing shows both railroads' trains, but the NYC only shows the NYC trains.

T773 is not a train number shown on either of the schedules.

The NYC schedule is Page 230 while the PRR schedule is Page 420.
