Allyn-only the phase 3, 4 and 5 were stock offerings
then
NH and Southern were custom -the NH is prototypical and 4 exist-#228-231
we have yet to hear of others, if any
-theres a link to york based shop -take a look
i see amtrak running along the SF lines south to Pueblo out of Denver
these are cross country trains, not east coast short hop intercity commuter trains-they are often 10-12 cars and clip along about 70-90 mph if i can estimate based on my car speed (road parallels trackage)
-most often what i see are the double headed locos, 1-3 'material handling' box cars-(ie mail) and the double level cars -these are almost always behind the engines out in the west-ive never seen them at teh ends as they are on the east coast trains-i imagine its simply shunting-east coast often has one ended stations so its easier to grab the end car-the western stations are usually thru platforms so either end will do-just my speculation
these really are a nice LGB offering-just about as deluxe as any of the german or swiss LGB models (but for the low quality plastic-more like a styrene)
i have always thought LGB prioritized with the best premium features for the models in response to their larger german market-i always thought that by comparison the US items got comparatively somewhat short shrift on minor details-ie opening windows, interior detail, lanterns, platform gates-even the US smoothside coaches were rather simple and plain
