Our layout has been operating quite well recently, with the
phase problems solved and not repeating for a couple of
months. However, we recently started testing a few passenger
trains, and we are running into a curious problem with lighted
Walthers passenger cars.
Although a string of up to four locomotives pass from one
block to another with ease as they straddle two independent
blocks, even those junctures crossing blocks powered by
different boosters, the Walthers lighted passenger cars short
out the blocks. When we insulate one set of trucks (putting
tape across the contacts), the problem goes away, but then we
get flickering lights across the blocks.
Has anyone else had this problem? Causes? Solutions?
