Things just keep getting curiouser and curiouser. Currently up for auction at Mr. Muffins is a Weaver #QC1079-LP (as opposed to -LS as noted above) for a B&O Cincinnatian 4-6-2 (a Beauty) with Protosounds and a DCRU for reversing. But, based on what I saw earlier with the two Hiawatha engines, -LP should have stood for Railsounds and TMCC equipped. Could it be that the -LP stood for 3-rail with Protosounds, and when Weaver switched over to TMCC and Railsounds, they just kept using the same codes? Wonder if they ever changed that code after 2001 to reflect the TMCC / Railsounds switch (like -LT or -LR)?
