Warner was an interlocked crossing of the MC spur to the Monroe waterfront, and the Detroit & Toledo Shore Line just north of Monroe.
Image info: This is D&TSL train 707, led by #76, a GP-7, at Warner in 1980. Note the gate at the left which is moved to allow MC trains to access their spur. [Charles Geletzke Jr.]
This was a half-interlocked crossing. The D&TSL was protected by signals. The MC spur was protected by gates which were connected to the signal system.
This was near the MC's Warner Yard.
