Tesla's Germany factory is going to have a train service that will transport its workers for free, which cool, train good. But a number of the usual suspects (Teslarati and other Tesla/Elon loving media) are claiming that Tesla are launching the train as if it had built the train. In some cases adding its "mind-blowing" capacity (its the same as a regular train).
Here's the kicker: Tesla only slapped its name on a train built by Seimens, using batteries manufactured by Toshiba
To add to this, the most successful locomotive lineups in American freight and passenger service (SD, GP, F) were manufactured by GM for the longest time before being handed off to another corporation. So naturally it was in their vested interest for trains to run on oil.
