Normally just the through train from Saginaw to PH and return, and the local. PH&D coal trains and empties were run as needed. Prior to the 80's, they would sometimes run an extra through train. What became PH77 in the late 70's was usually called out of Sag around 10:00 PM and got to PH around 2:00-300 AM. The crew was taken off duty for 4 or more hours and called back as SA37 to Sag. The local ran east on M-W-F and west on Tu-Th-Sat, normally called for 6:00 AM on both ends. The night shift at PH was the busiest, with 3 or more round-trip "floats" across the river each night -- load and unload the boat -- break down PH77 and build SA37.
