[3] Like the PW&B mainline, the Fall River Branch was completely electrified in 1900 with a 600 Volt DC single-wire trolley system under New Haven ownership.

The New Haven had originally envisioned the eventual electrification of most commuter rail lines in the South Coast of Massachusetts; however, these plans were indefinitely postponed due to cost.

During rush hour periods, the battery station would pick up some of the power load, easing the burden on the Warren powerhouse.

The Fall River Branch was beginning to see a steady decline in ridership by the early 1930s with the onset of the Great Depression.

In January 1932, the Slade's Ferry Bridge was disabled when a passing ship attempted to navigate past the swing section and collided with it.

[7] An expansion of the bike path in Warren began in 2021, including the rebuilding of the former bridge over the Kickemuit River, left destroyed after the 1938 Hurricane.

The former Brayton Point battery station remains abandoned a few hundred feet west from the Somerset abutment of the former Slade's Ferry Bridge, though most of the structure is obscured by foliage.
