Following a route dispute with the Shore Line Electric Railway, the Branford Steam Railroad built an extension southward to a dock at Pine Orchard[2] on Long Island Sound, which remains in use today to transfer stone to barges for distribution.

Fisk, who sought to improve on this horse-drawn service, in December 1902 petitioned the Connecticut General Assembly, the state's legislative branch, for permission to convert the railroad to steam power.

[8][9][10] In 1900, the creation of the Palisades Interstate Park Commission of New York and New Jersey forced the closing of basalt quarries along the Hudson River.

[17] After much argument, the house and senate overrode the governor's veto on July 16, allowing the modified charter to take effect.

While the modified Damascus Railroad charter allowed Fisk to expand rail operations northward, he also sought to expand the Branford Steam Railroad's tracks southward to a dock he owned at Juniper Point on Long Island Sound (between the Pine Orchard and Stony Creek neighborhoods of Branford).

[20][21] On April 29, 1909, the Connecticut General Assembly approved the amendment to the charter, allowing construction to proceed southward and the BSRR to take direct control of the Damascus Railroad.

[21] The Branford Steam Railway received permission to build its extension to the coast by crossing most streets at grade (on the same level).

[21] Three days later, the Shore Line responded with its own petition requesting approval of its planned route, crossing the BSRR at grade.

[21] Shortly afterwards, a third petition was submitted to the commission, this time by two selectmen of North Branford who were in support of the Shore Line's proposed route.

[21] The Shore Line refused to accept this, and filed a nearly identical petition to the commission shortly afterwards, this time with the direct support of the two North Branford selectmen.

[23] Fisk promptly sued, and following an emergency summons again obtained an injunction forcing the Shore Line to cease construction.

Within the quarry itself, several 15-short-ton (13.6-metric-ton; 13.4-long-ton) 0-4-0T saddle tank locomotives hauled excavated stone in gondola cars to the plant's rock crusher.

[4] Two heavier locomotives, a 4-6-0 and 2-6-0 (BSRR 1 and 2 respectively), were used to haul crushed stone from the quarry, either to Juniper Point for loading into barges, or to the New Haven Railroad interchange in Pine Orchard.

[4] The two saddle tank locomotives continued to perform switching duties until January 1960, when the company bought another 44-tonner from the New Haven Railroad.

[4] The Branford Steam Railroad purchased a new EMD SW1001 in February 1976; the locomotive was delivered in red, white, and blue paint to commemorate the United States Bicentennial.

[33] In 2009, the State of Connecticut applied for a Transportation Investment Generating Economic Recovery (TIGER) grant on behalf of the Branford Steam Railroad.

Some aggregate is transferred to the Providence and Worcester Railroad at the Pine Orchard interchange, but the majority is brought to the docks of the Buchanan Marine Company (like the BSRR, a Tilcon Connecticut subsidiary), where it is loaded onto barges.

Tilcon Connecticut uses these barges, operated by subsidiary Buchanan Marine Company, to transport aggregate to locations across the Northeastern United States.
