C via Concourse.
A Manhattan-bound C train using R68 stock (Westinghouse-Amrail, 1986-1988) is seen arriving at Fordham Rd Station on the IND Concourse Line. On this particular weekend, C trains replaced D trains in the Bronx due to track maintenance work in Manhattan, which, combined with C trains using equipment from the B and D, drew buffs from all corners of the city.
