[2] Around 1916, the BERy constructed a pair of loops on the north side of Commonwealth Avenue just west of Lake Street; this allowed use of two-car motor-trailer trains on the line.

[8] Boston College station has not had MBTA bus connections since the 535 Lake Street–Auburndale route (the direct descendant of the Commonwealth Avenue Street Railway) was discontinued in 1976.

[12] Not a separate station, they were used when congestion in the yard (common with the introduction of the new Boeing LRVs) prevented trains from entering or exiting.

Portable lifts were installed at Boston College around 2000, along with a wooden mini-high platform (for level boarding on older Type 7 LRVs) on the inbound side.

[15][16] By 2005, the MBTA planned to relocate the station to the median of Commonwealth Avenue, just east of the Lake Street intersection.

[17] Boston College later agreed to aid the project financially and to donate land to widen Commonwealth Avenue to accommodate the station.

[18] New raised platform allowing level accessible boarding on newer low-floor Type 8 LRVs were completed on the existing site in 2009 at a cost of $296,000.

[22] A design shown in March 2024 called for the maintenance building to be removed, the yard tracks reconfigured, and a traction power substation added.

Boston College station would be relocated to the median of Commonwealth Avenue, with a single island platform east of Lake Street.
