Summary[edit]
DescriptionAyer Interlocking Tower September 2022.jpg |
English: The old Boston & Maine Railroad Interlocking Tower at Ayer in September 2022. This tower once controlled movements through Ayer Junction, where the east-west Fitchburg Route intersected the north-south Worcester, Nashua, and Fremont (WN&F) Division as well as the Groton Branch Railroad. Today, the Fitchburg Route remains in use for MBTA Commuter Rail service between Boston and Wachusett Mountain, as well as freight service west of Wachusett. The Groton Branch and the southern leg of the WN&F Division also remain in use by CSX and Norfolk Southern for freight service. The northern leg of the WN&F Division has been abandoned, but lives on as the Nashua River Rail Trail. |
