Huntsville and Madison County Railroad Authority U23B HMCR 9554 with two covered hoppers in tow is about to pass B23-7 HMCR 3986 in the railroad's yard in downtown Huntsville, Alabama. Both locomotives brought the two covered hoppers north. The 3986 was cut off and put into a siding so that it could be used to switch cars from the south end of the yard once the rest of the train clears.
