I am someone who think that the direction that Amtrak is going in with the Siemens Charger fleets of long distance locomotives is that of a circus instead of a railroad. With the recent issues with the ALC-42s, Amtrak should have looked in the past for inspiration for the future. I would have loved to see them go with an F40 designed to meet tier-4 requirements. A work horse like the original, this model would have upgrades that would benefit crew and save the railroad cost dealing with a completely different animal. I think that the Charger class of locomotives are decent for commuter and regional service, but I have seen very little to believe that these units are not going to have issues pulling the Auto Train.
