Good evening,
I just purchased a used BNSF SD75M locomotive. It seems to run pretty well but I have a question about the headlight. The light from the headlight shines pretty brightly through the cab windows; is it supposed to do this? Any help would be appreciated. Thanks for your time.

Paint the inside of the cab black to stop the light.

Will that actually fix it? Flat black?

Yes, flat black will do. If it still leaks, apply another coat.

It isn't leaking through the shell, it is bright in the windows. I don't think painting the interior is going to fix that issue.

Have you checked the voltage output of the light? Did the previous owner install a new light?

Tamiya X-26 : *thin coat on the led.
Tamiya X-19 : *thin coat interior cab windows.
*applicator: toothpick.

The SD70M has a cover for the front windshield. It’s a gray part with seats.

So, what is the best way to remove the shell on an SD75?

So, what is the best way to remove the shell on an SD75? I always use toothpics and "persistent finesse". Don't man-handle the thing, just sort of gently nudge things until you start getting the shell to ease off the mech. The toothpics are a good way to carefully spread the shell apart from the frame to get things started. I scanned the diagrams from one of my SD70's and I'll see if I can post them here in case that helps. Stand by. See Post Below.

FWIW, I find using flexible guitar picks works really well for shell removal; got the idea from the "Z Trains Weekly" blog, I think.

NOTE: The attached image is related to the 1st gen SD70M/SD75I. I'm not sure what the differences are in the later units so--as they say--"your mileage may vary".   |

Dave,
If your lighting board is the same as the drawing Doug posted, using the T1 type LEDs, you can cut yourself a piece of heat shrink tubing, about 5/32" long, and slip it over the LED.

It's very easy to remove their shell simply holding cab between two fingers, and the locomotive's fuel tank between two others. Dom |

Dave,
Did you ever get your light-bleed issue fixed? I'm seeing the same thing as you on my BNSF SD75M- light flooding into the cab.
Thanks,
Ajay
