Signals Tutorial (YouTube)

  Feb 5/19: I came across these videos on YouTube presented by a railroader living in Alberta. They do a great job of explaining Canadian Railroad signals.
  * Part 1: The basic three light system.
  * Part 2: 1 and 2 head systems.
  * Part 3: Diverging and Limited speeds, to and at signals.
  * Part 4: Dwarf (Low-Mast) signals.


  At the suggestion of a friend I've rewritten my mobile app to work in a browser and made a few improvements.

  The upsides are easier maintenance and it's available to a wider audience. The downsides are that I'm no longer being paid for the app and you need to be online to use it.

  Would you like to make a donation? $5 CAD is the suggested amount, but you can change the amount to whatever you like.

** If you'd like to get the Android version (for offline use) it's still available at Google Play. The Android version does not have the "Full-NB" option.
