Hello, what do you mean by "hard wired pickups on the trailing truck"? I am planning to purchase a used 4-8-4 Niagara (standard Bachmann) and am wondering about general quality, whether it will be able to negotiate a spot on my layout with 18 inch radius curve (the tender is the going to be the problem I think; unlike Bachmann tenders, Rivarossi tenders of this type - e.g. on their Big Boy - had truck wheels that moved laterally to negotiate sharper radius turns), and whether the electric pickups on this loco only (none on tender) will be adequate to permit smooth running over multiple adjacent switch and crossing tracks. Any thoughts on these matters? Thanks!
