The Cincinnati, Dayton and Toledo Traction was an interurban which operated in Ohio.

It was itself leased in 1905 and dissolved in 1918, when its line was taken over by the new Cincinnati and Dayton Traction company.

They in turn formed the Cincinnati Northern Traction company, which leased the CDT in 1905.

[2] The Ohio Electric suffered financial problems throughout its existence and began selling off lines in the late 1910s.

In 1918 it spun off the CDT's Cincinnati–Dayton route to a new company, Cincinnati and Dayton Traction.
