<p>[quote user="Datafever"]Is third rail electrification a viable solution if grade crossings are present?[/quote]</p><p>You can theoretically use third rail if a fail-safe way can be invented to only activate the third rail during locomotive pass over, e.g. the power line is buried underneath the third rail, and the current is transfered to the third rail by relay triggered by the locomotive passing over it.  Basically you're using the same technology as is used to activate crossing signals.  Problem is, we all have seen crossing signals go off on their own sans an actual train triggering it, and obviously you can't have a third rail becoming electrified due to the same causes.</p>
