I just thought I would take the time to impart what I have learned using Super Street "Y" sections I have two in my reverse dogbone. My Super Street Taxi would derail consistently when entering one or the other sections of either "Y". Basically the wheel flange would consistently or randomly strike the guard rail causing the vehicle to either derail or skitter over the rails. This condition left the points in mid position ensuring a derail on vehicle return. I fashioned a lead-in from spare Super Streets center rail and inserted/glued this metal piece into the road bed groove side as a lead-in to the guard rail. This eased the wheel flange into a graceful (successful) position as it approached the guard rail. It worked.
