Been trying to post for two days, finally found a "work around" that works with dial-up (use "reply with quote"!)
Bob, good point about requiring a passenger car set. Granted, N&W used smooth-sided cars & I'd love to have some in S--the Shasta Daylight, which used PAs also used smooth sided cars & that's my childhood train. But, given the cost for tooling a loco, I think the AF cars painted maroon w/black roofs would look grand behind a J.
As to all the "Bells & Whistles" my Daylight painted RB type uses all period equpment, puffs smoke, choo-choos and has directional lighting even (I add a tender light & by wiring the reverse unit just so, the headlight dims a bit and the tender light comes on in reverse.
Not saying that Modern engines should use the old tech, but the amount of "features" now felt to be needed seems a bit excessive. Electro couplers especially! Years ago I was running my Y-3 on a friends layout, and my sister came into the room--now she's not a train person by ANY means-- and I asked her what she thought of the sound effects, 'Sounds like a recording" was her response--she preferred the old ACG choo-choo units (but then that's what she grew up hearing when I ran my trains, so maybe that influenced her preference).
As to the PE sets, I find it very interesting that the complete PE set, with track & transformer is "street price" only a little more than the price of a single Berkshire Locomotive. I would think the individual locomotives would have to have more features to justify the price. OTOH, just the two add on cars are about 1/3 the price of the whole set!
Gary, I vote for a Cab-Forward too!!
