Jointed Rail ATSF F7A has great dynamic brakes, and realistic in cab sounds, and Mars Gyrolight.
I ran an A-B-B-A set down ''The Slide" (an 11 mile grade on the Horseshoe Curve) with a 11,000 ton train in tow, with 2 helpers on the rear, and the dynamic brakes acted very realisticly, and trainhandling was very challenging using dynamic brakes in CAB mode.
