[@HunterWilliams-le9bk]

Why can’t any of these Montana Rail Link SD70ACEs lead a train?

[@AlexTheRailfan]

@@HunterWilliams-le9bk They do not have Positive Train Control (PTC) installed on the locomotives. Plus, those are Thundercab locomotives and BNSF is not planning to add PTC to the locomotives since they’re not big fan of Thundercabs.

[@HunterWilliams-le9bk]

@@AlexTheRailfan does that mean only Montana Rail Link SD70ACEs 4400-4408 will get PTC, because those units have isolated cabs and they have Raised Letter K5LLAs.

@@HunterWilliams-le9bk Maybe, yes, you are correct that they have isolated cabs and there’s a high chance that they’ll get PTC.
