NKP 759 Steamtown extra northbound passing through North Chelmsford Interlocking. Point of interest here is that it shows the four tracks that ran between North Chelmsford and Middlesex Interlockings. Tracks from left to right were numbered 3, 1, 2, 4. Track 3 (next to River) was unsignaled. The other three tracks were controlled by Lowell Tower.
