mac 4884 <br /> <br />What big boy are you running up that 5% grade? I have a Trix and can barely pull 8 forty foot NMRA weighted boxcars cars up a 4% on 22" radius!!!! It will just barely pull 4 Rivarossi Streamline passenger cars up the same grade! Gets near the top and just spins!!!! The Trx will pull 40+ cars on the level. My Rivarossi 4-6-6-4 with traction tires can only pull 16 cars up the same curving grade. <br /> <br />My new layout will have a maximum 2.5% to aleviate the serious slippage.
