Only if the engine is cold and isn't designed for start/stop. There are Prius taxis which have start stop with mileages right up into the 300k region without any drivetrain issues. The cabin will be trashed, but the engine is fine. Part of that is just general Toyota bulletproof mechanicals, but those engines will have been through hundreds of thousands of starts with no ill effects.
The wear occurs because the parts aren't coated in oil. Once it's running and isn't too cold, then it's no issue. I believe that VivaRail are using the 3.2 diesel that Ford put in the Ranger pickup. Which I'd assume has stop/start, so it would make sense to utilise that.
