........from zero revs. Just in case you weren't sure - getting your hands on a flat torque curve is a good thing. Being a novice I was sadly denied the opportunity of hauling some rolling stock to fully appreciate the joy of steam power on this occasion - but frankly, load or not, winding this thing up was a hoot. When you get anywhere near a chance to have a go, fight your way over the push-chairs and get to the front of the queue regardless.
