Erik; What type of starting does the D8800 have, Air, Electric or Starting engine? I like those hand rails on side of hood. Do they get it out and run it? Bill Walter

I was there in about 03' They placed a thread on the BB looking for a part for the engine. At the time I was working at the Navy Hospital in Beaufort, SC , so I had to check it out. There is loads of neat stuff there, old machine tools, engines, etc. As I remember, the President of the RR (way back) was the father of the lady that started the Girl Scouts of America.

according my book the 8800 is a 4 cilinder diesel engine and by the looks of the radiator it is the same engine as the RD7 from 1935, 1936 0r 1937.
probably its pony start.
today cat has new locomotives in their program.

Typical of all electric traction motor driven locomotives.
They start the engines through the generator with batteries.

Davenport did build diesel-electric locomotives but this locomotive, typical of many such small industrial locomotives, did not have electric traction motors or a large generator. They used a 4 speed (each direction) manual transmission driven directly off the back of the clutch by a universal joint. Davenport used their own design of manual transmission that had the rear axle running through it to power it. The transmission could move up and down if it was on uneven track. It had siderods to transmit the power from the rear axle to the unpowered front axle. Chains could also be used to power the unpowered axle, if the customer specified it. It was called a diesel-mechanical locomotive. Most of their later models had a torque converter instead of a clutch. Of course, they could use gasoline engines if the customer requested it. The D8800 engine itself weighed some 2-1/2 tons, so that helped give the locomtive some needed weight for traction. Modern replacement engines do not usually weigh this much and tend to cause these little locomotives to be "light on their feet" for traction.
Starting the D8800 was by pony motor on the side of the big block or a battery operated starter in that position. This particular locomotive was built for TVA in Oct. 1940 and weighed 10 tons and was last used by them at Singleton, TN.

Thanks for the information about the power train. Very interesting. I love the fact that the Cat radiator is stuck out there like it is. So it is not in running condition as of now??? Does anyone know what the problem is?? Bill Walter
