Ted S posted:Replace the batteries. You can also search this forum for something called the YLB (Your Last Battery.) I think it's some kind of capacitor that won't ever leak or degrade to the point that it won't take a charge.
Ted, thanks for the plug, but the YLB is for Lionel RailSounds, not MTH. The BCR, while also using supercap technology, requires a charging circuit in the locomotive, the YLB replaces the alkaline battery in Lionel Railsounds equipped locomotives.
