Get one of the new Deere 18L to power it that doesn't require emissions controls And it should be able to run enough power to make the batteries stay charged well. Batteries are great on a locomotive where they need added weight anyway. Won't need so much ballast when the ballast is built in in the form of batteries.
I hope soon they will make a trip back to Texas and run the old T&P route like they did a few years ago . It was absolutely awesome to stand next to this Beautiful Behemoth in Marshall , Texas
Caught your fireman sanding the flus!! Does Big Boy use a drift valve or do you use the diesel helpers dynamic system? Likely Mr Dickens or his team don't actually read the comments but heck who knows!!
