QUOTE: Originally posted by Berk-fan284 Hello all, my question is for anyone with first hand experience or knowledge of the BLI Quantum Engineer. In specific will it work with the older BLI locomotives such as the N&W Class A 2-6-6-4 and the PRR M1a 4-8-2 and would it work with the Lionel Challenger (hopefully) also? In my present situation I only can setup a temporary layout (on the basement floor) so that precludes DCC for the foreseeable future before anyone mentions DCC.
