According to
interlocking track diagrams at the Michigan State Archives, the Michigan
Central east-west main line was still single track in 1898 (west of
Albion). The first interlocker was apparently installed at that time
and the tower at Albion was known as Tower "A". Letters were often
used to describe towers and stations as a time saving step when using the
telegraph. The Michigan Central operated on a manual block system at
this time.
By 1919, the MCRR was double tracked through Albion and sidings had been added east and west of the interlocker. In 1925, pot (ground level) signals replaced semaphores on some tracks. The MCRR ran dozens of trains in each direction, but the LS&MS was down to two passenger trains each way per day, and perhaps a freight or two. The LSMS and MCRR both were under control of the New York Central, and most traffic between Ohio/Indiana and Lansing and points north were being routed via Jackson (or Detroit). The LSMS route became less and less important during this time. In 1926, the NYC (LSMS) mechanical home signals were replaced by semi-automatic signals. Manual block signals were removed. A "S-8" lever machine was installed with 1 working lever which allowed movement on the MCRR or LSMS. In 1930, the signals on the LSMS were removed as were all derails on the MCRR. Stop boards were installed on the LSMS and derails remained to protect the MCRR crossing. Controlled switches were also removed, along with the wye signal. Derails on the LSMS were controlled manually from an electrically locked lever at the crossing. The electric lock on the derail lever was controlled by the operator at the MCRR, as were all MCRR signals. Siding switches (west of the crossing) were electrically operated by the operator in the depot as well. The tower was closed, and used as a relay station. All trains on the LSMS (now NYC) stopped at stop boards. Trainmen were instructed to communicate with the MCRR operator for release of the lock on the derail lever. All signals on the MCRR were required to be in the stop position before the electric lock on the derail could be released. Derails on the NYC must be in the derailing position and their lever locked before any signal on the MCRR could be cleared. Indicators to show the approach of MCRR trains were located at the crossing and at the station. The operator was unable to unlock the NYC derails when track circuits within the home signal limits are occupied. The MCRR signals were also blocked from showing clear when the NYC track circuit through the crossing was occupied. Train order signals were moved to the right of the mast on the main signal masts (east and west). In 1962, the interlocking was completely removed and the crossing eliminated. All switches were changed to hand operation.
