my layout has been expanded 4x8 it includes 2 crossovers l&r 2 turnouts l&r all dcc ,all programming went really well including reversing one loco.my derailment problems are when the loco and cars are going into the c/o and t/o at half speed or a little less it runs through good sometimes then goes off. i changed the order of the cars i only have two and a caboose so its always car two and three i also played with direction and speed. i did notice the points moving but its hard to catch it and see the actual derail is it normal for this movement? also i can see that the manual slide has moved a bit, also its like there is no pressure applied to keep the points in position towards travel direction is there a way to tighten this up.also when i power up some switches activate others don't seem to? so i am checking to make sure of direction any tips or trouble shooting ideas would be welcome thanks ahead of time!
