“Cola Tower” The Cola tower was built in 1938 during the electrification to centralize traffic control on this freight network. Cola tower in Columbia controlled all trains on the Columbia Branch to Lancaster, roughly forty miles of the Columbia & Port Deposit Branch including the junction with the A&S Branch at Port and the York Haven Line west to Shocks Mill. Cola’s jurisdiction over the C&PD was unique in that most of the line was actually under control of the Baltimore Dispatcher and was considered part of the Chesapeake Division, while Cola was part of the Philadelphia Division.
