Joe-
Q.E.D., unfortunately. Well, if Philly is the dead end you predicted, how about returning to the fountainhead of O-scale subways, i.e., the Big Apple. If anyone has his finger on the pulse of MTH, it is clearly yourself. Given MTH's prolonged dormant period, there seem to be only two directions left: newer models (expensive) or the one missing link in the older collection- the R15 everyone has been seeking for years. Any chance?
