CN 123 has a somewhat old school lashup (by 2022 standards) of SD75I CN 5784 & Dash9-44CW CN 2548 as it heads west on the North Track of the Kingston Sub.
There's colorful Fall foliage in the valley, with CN 122 crossing the valley on the Salmon River Trestle. One of my favorite spots to photograph while in Northern New Brunswick.
