Bruce, thank you for the warm welcome and the great resources! This is exactly the kind of help i have been looking for!
To answer your question:
This is complicated, due to the fact that that the survivig ET&WNC steam locomotive was separated from its (semi-abandoned) railroad line more than 60 years ago. The loco now runs at a nearby theme park called Tweetsie Railroad. The survining ET&WNC track is partially located in a Christian summer camp at Doe River Gorge and has been under volunteer restoration since 1995 or so (a HUGE labour of love on the part of the volunteers).
Bachmann makes two versions of the loco and two sets of accompanying rolling stock –
(1) a 4-6-0 Baldwin loco, ET&WNC-marked, with a logging and gravel-hauler freight train set with caboose (incorporating cars marked with the logo of the Linville River Railroad, which was historically linked to the ET&WNC), plus a separate set of 4 ET&WNC marked passenger, baggage, and excursion cars.
(2) a 4-6-0 Baldwin loco, Tweetsie Railroad marked, and a train set hauling Tweetsie excursion cars, as at the theme park.
I have purchased the Bachmann ET&WNC-marked (as opposed to “Tweestie Railroad” marked) 4-6-0 locomotive, four Bachmann Jackson & Sharp passenger / combo / parlour / baggage cars, a Bachmann Linville River box car, ET&WNC bobber caboose… and am working my way up from there. I think i will end up with two consists – freight and passenger/excursion. I will not run any theme-park marked stock, only ET&WNC / Linville River and maybe a Southern hopper car (the Southern now runs a switching operation with standard-guage diesel engines on part of the old ET&WNC territory, and i happen to have inherited a small block of Norfolk and Southern shares from my grandmother, which i treasure).
I am still in the layout planning stages, and as far as the Garden portion of the program goes, i am combinng features of both the remnant ET&WNC road now operating as Doe River Gorge Railroad (the Christian summer camp that is restoring the physical track, tunnels, and spectacular river gorge bridges, but has no actual “train” and only runs ET&WNC-marked ugly motorcars) and Tweetsie Railroad (the well-known family theme park that operates the original steam-powered ET&WNC loco #12 (plus an Alaskan steam loco) – on a fairly bland 3-mile loop of track laid in the 1950s).
The Tweetsie Railroad theme park trestle – which, yes, is a fairly conventional style – is the one i will be modelling, although i am entertaining the idea of creating the destroyed and abandoned Doe River Gorge Bridge (at the summer camp) along with workers repairing it, which they are doing right now in real time.
The ET&WNC had, at its height, 13 locos, numbered 1 through 12, plus number 14. They skipped number 13. Only #12 survives, and this is the one Bachmann copied.
I am going to customize my Bachman loco to reflect the never-used Number 13.
So what i am looking for is a simple G-scale plan for the 1957-built Tweetsie Railroad theme park trestle in Blowing Rock, NC.
After that, i am looking for help designing the destroyed Doe River Gorge brige of 1901, in the process of being rebuilt.
Dang, that was complicated! Also, forgive me for any errors – and please correct me, anyone! – as i am a gardener with no railroading experience.
Thanks for asking!
