I wonder if they could retrofit the M-7A's with blowers on the ends of each married pair and have the leaves get blasted away before they get crushed by the train wheels.Most of the problems are with the slimy residue already on the railhead from previous equipment...not leaves immediately coming down in front of that train, so blowers wouldn't work out well. Best way to combat it is plenty of sand (standard equipment), or maybe it's time to get both waterworld trainsets out and about!
