[3] It was formed by twenty local individuals, including Lorenzo L. Shaw, Herbert Merrill and Seth L.

[4] Its trolleycars ran every fifteen minutes for a one-hour journey from Portland, the state's largest city, to Yarmouth, a coastal town on Casco Bay's northern shores.

After crossing a predecessor of today's Tukey's Bridge (the construction of which delayed the line's opening) and the second iteration of Martin's Point Bridge,[2] its route north of Portland followed in parallel the Atlantic Highway (today's State Route 88) through Falmouth Foreside (stopping at Underwood Spring Park and its casino),[5] then, at the former Westcustogo Inn, took a left onto Pleasant Street shortly after entering Yarmouth.

[6] At Yarmouth, passengers could alight and board a Portland and Brunswick Street Railway car to continue up the coast (via Casco Castle in South Freeport).
