I have Bachmann track pack of Madison central. it has 4 switches on layout. we have derailed in the switches quite a few times for only getting started. altho we do not have the electric to the swithes but does not appear that the switches vibrate open. one derailment was with 4 coal cars going thru switch into the siding and my best guess is in the frog of the switch it let the wheels come out.?? any ideas on my derailments.it does it with just engine on the main loop after a few times around also. thanks for any tips advice.

just wanting a train layout and think this is way to go for me. any advice/thoughts on the Bachmann track pack in nickel?alot on amazon say swithches are not good.one thing I have noticed is atlas and Bachmann are associated with micheal gross,,,does this mean same company?thanks
