Years ago while railfanning shortlines in Oregon, I photographed what my references called the Peninsula Terminal RR in Portland. Reporting marks on the locos were PTRR though the reporting marks in other references are just PT. There are also many resources for a Portland Terminal RR with reporting marks of PTRR. Some discussions and references say this road still exists to some extent. Anyone know if the Peninsula Terminal and Portland Terminal are indeed separate entities or is there a mixup somewhere?? Thanks to anyone who can clear this up for me.
