Hey Guys:
Does anyone know the purpose of the protrudeances on either side of the nose of the Tyco Davenport Switcher shell?
Thanks,
Gareth

The Rad is right in front of that so maybe related to that. Covers for coolant hoses?

I was searching on Davenport images after reading this topic,and ran across a forum that mentions an abandoned unit around Baltimore, MD, Curtis Bay area. Here's a link to it.

You can clearly see the engine in the wooded area just above the freeway. Apparently used to be a recycling facility for old locomotives and parts years ago by a company called Striegel Supply Company, here's a link to the forum as well.

Gareth, that's a Plymouth MDT. I'm not sure what the protrusions are.

Jerry, that Davenport looks the closest to the AHM GE Center Cab of any prototype I've seen. Most aren't boxy enough.

Hey Nelson:
I meant plymouth but I think Tyco calls it a Davenport doesn't it?
Looked at about 40-50 pics on line and still can't figure out why the "blisters" exist at the front sides?
Assuming it's an inline diesel, there's a rad in front so I'm thinking something to do with cooling, or an aircannister for air filtering but they are symmetrical.... Hmmmm

Gareth,
The Davenport looks like they used the MDT shell (minus those protrusions on the hood) and put side rods on the chassis.

I think they're cool, but I don't think it had a prototype.
Tyco just called the Plymouth MDT a diesel switcher, according to Tony Cook's site. They copied the AHM MDT, which came out on '65.
Those housings could be for part of the radiator assembly. You can see they have access doors on them in the prototype photo. Why so curious?

I'm gonna say...
Winterization hatch... the front grill would be closed while the heated engine air would be recirculated to the intakes.
Fuel burns better when heated.
(Early 1980's GM auto's had a plastic/metal fuel-heater grate between the carburetor and injector fuel distributor ports.)
This would be a gas-electric locomotive.
Diesel fuel would not work well under very cold conditions, especially on these very small units.
There's a geared pulley system below the deck, just ahead of the wheels... blower ducts from the electric motors on the axles.
There's an air-pressure valve just below the air tank of #14 pictured... perhaps a bleeder valve for condensation.
These tiny locomotives had to be very self-sufficient and economical at the same time.

I don't have a one track mind. It depends on the turn-out.

Is that a power-trip or just another pick-up line?
