If you think you've found a bug on the website which isn't specifically an App or Map Editor problem, or have a request for new or modified feature of the Community, Forums, or Waze website, use this forum.
Yes, please don't. Using Waze on a train can result in you polluting real traffic data on adjacent roads. Google Maps is more than adequate for what you probably want to do - review progress - although it doesn't give you the train's speed. You can get that from a GPS Test tool.
