Finally found a way to make a lens shade for my Canon PowerShot digital camera that will (when placed against the train window) block light reflections from inside the car, preventing them from becoming part of the recorded image (still or video) and degrading the image quality:

It's made from a shock absorber boot that's fairly flexible with an end small enough to be trimmed for a secure fit on the extended lens housing. It also extends far enough in front of the lens housing so that the camera can be angled almost 45° without breaking the light seal. The boot was cut with an X-Acto #11 hobby knife and the flange at the end trimmed using a pair of curved cuticle scissors. The difficult part might be finding the correct size boot to fit your camera. I made it easier by first measuring the OD of the lens housing and then turning down a fender washer to that same diameter. Attached the washer to the end of a bolt (for a handle) and used it to find a boot with an end just small enough to be trimmed for a light yet secure grip on the lens housing.
Can't wait for my next train trip to try it out!
