weaverton Miller...
Below is the module through Miller.  The Cherry Run module attaches to the left of this piece and the Potomac Air Park module attaches to the right.

Miller is controlled from Miller Tower located just off the right of this picture.  Miller Tower, abbreviated "R" Tower, controls the switches to the No. 4 low line, the two old main lines and the connection to the Western Maryland main line.

This is not an important interchange until the Chessie Era when it made more sense to ship over your own affiliated lines then to pay the costs of interchanging to Conrail.
