Built in 1901 and closed in 1932 for a good 30 years of operation. The D & T drove the development of the Northridge area, and also suburban development for points north.
The builders were the Clegg family (local industrialists and real estate speculators) and Valentine Winters (a banker who was involved with other traction lines out of Dayton).

It's unclear where the stops were. The map below is a best guess based on available sources. There were three stops in Vandalia, at least two in Chambersburg, renamed Murlin Heights, after the traffic director of the D&T. There was also a stop at the cematary between Murlin Heights and Stop Eight.

The line also ran a local service as far as Murlin Heights/Chambersburg, were there was a turn-around loop. Presumably this local made more frequent stops to serve the plats that made up Northridge.

The line was a mix of single and long runs of double track. Suprsingly the section through Northridge wasn't double-tracked as there is an account of a grisly accident on single track: A fast moving northbound regular train missed signal or train order, rammed a stopped local car and partially telescoping it, resulting in injurys and deaths.

D & T Rolling Stock

The alpha and omega of the passenger equipment. Top image is an early Barney & Smith car (made in Dayton) from 1902. As one can see this resembled standard railroad passenger coaches, as did most early interurban equipment. Dayton-based B&S used to specialize in passenger cars, but moved into interurban busines, which kept it alive into the 20th century.

The bottom car was the last passenger equipment bought by the D&T. Built by the Cincinnati Car Company in 1929, it was nearly the last word on interurban design. Built more like a streetcar, with the front and rear folding doors and lower floorboard. It looks fast, and had a eye-catching orange and maroon color scheme.

Electric Fast Freight

Most interurbans had some freight buiness, usually "less than carload", or LCL, freight. These were usually handled by baggage compartments or "box motors", like the car below. Sort of a powered freight car.
