I took my MTH 0-8-8-0 Erie Camelback to Mercer Junction to have Dave Minarek install a BCR to replace the two AA rechargeable battery setup in the tender. Then we tested the locomotive on Mercer Junction's store layout. Dave and I were not happy with the sound quality, so Dave quickly(and cheaply) installed a new speaker while I purchased a few items. As Alan Miller of OGR says, "Having a great LHS is so important."
Dave and I both have a P&LE A2 Berkshire that are among our favorite locomotives, but the visual action of the Camelback got the other store patron's attention.
Enjoy the short video of the Camelback on Dave's layout. The video was taken before the new speaker had been installed.
