Moments after it pulls out of the station, chugging into the dense cover of the Monongahela National Forest, the Shay locomotive begins its climb.
The baking sun vanishes, the temperature drops and riders grow captivated by wildflowers, butterflies and a fearless fawn that stands on the track, staring until the last possible moment before scampering off.
When the whistle blows, white steam shoots skyward. And from time to time, a cloud of acrid black smoke wafts over the cars, the necessary result of burning 4 1/2 tons of coal for fuel. It stings the throat, but for John Grencik, it only adds to the authenticity of the Cass Scenic Railroad.
"I love coal smoke. I get it natural," says Grencik, a model train builder and the descendant of railroad workers on both sides of his family.
Grencik, 76, traveled from Bakersfield, Calif., to ride a railroad that draws 40,000-70,000 tourists between May and October, opting for the five-hour journey to Bald Knob, West Virginia's third-highest peak.
The personal attention of the crew, including an invitation to visit the maintenance shop, made the experience better than he'd hoped.
"If you want to see the scenery and see nature as it is — and you don't want to do it fast — I'd give 'em four stars," Grencik says. "It's gorgeous. You picture yourself 40 or 50 years ago, the way things used to be."
Cass Scenic Railroad actually comprises its own unique state park, 11 miles long and just 50 feet wide. At 7 mph, the ride is slow but steady. For every 100 feet the train rolls forward, it rises 9 feet. As it does, a spectacular panorama unfolds, with vistas across the Alleghenies, deep into Virginia.
"The views are breathtaking," says Dot Frank of Woodsfield, Ohio.
As she and other tourists gape and snap photos, conductor Bob Starke chuckles.
"I hear it every day, 'I had no idea we had this right here in West Virginia!'"
But West Virginia, with an abundance of log-, poultry- and coal-hauling routes, is an ideal place for railroad tourism. There are five scenic railroads, one offering three trains and routes.
Though Cass is popular all summer, crowds grow in the fall when the mountains turn gold, orange and red. Starke's crew runs five cars with 130 people on a typical summer day, and nine cars with 500 people in October.
Chris Guenzler, who has ridden more than 1 million miles of rail since 1980, says there are more than 200 tourist trains nationwide, and "West Virginia has some of the best."
Guenzler, of Santa Ana, Calif., ranks Cass among his favorites, along with the Cumbres & Toltec Scenic Railroad in New Mexico and the Durango & Silverton Narrow Gauge Railroad in Colorado.
New routes open almost every year, but Guenzler says there are challenges to staying in business, including the high cost of liability insurance.
To keep costs down, some operators rely heavily on volunteer crews. They also must market routes creatively. Cass, for example, offers an evening dinner and music excursion called Fiddles and Vittles along with daytime runs.
"Some do Christmas themes, like the Polar Express," Guenzler says. "The thing that draws kids — although most of us can't stand him — is Thomas the Tank Engine."
In West Virginia's Eastern Panhandle, the Potomac Eagle Scenic Railroad focuses on its namesake, the American bald eagle.
"You'd be surprised how many people want to see an eagle," says train owner Dave Corbitt. "These are wild birds flying around, and you can't really count on them, but luckily, we almost always see one."
The Potomac Eagle follows the South Branch of the Potomac River into a narrow valley called The Trough, accessible only by boat or train.
"Canoeing is great," Corbitt says, "but it's not for everyone."
Trains, on the other hand, accommodate anyone from parents with small children to less agile senior citizens.
West Virginia's newest tourist train is the New Tygart Flyer, which runs on the Durbin & Greenbrier Valley Railroad.
The Flyer has two routes, one covering 46 miles over four hours, from Elkins to a roaring 18-foot-high waterfall on Shaver's Fork of the Cheat River. A 78-mile, seven-hour tour runs on Sundays out of Belington.
The enclosed, air-conditioned cars travel about 25 mph alongside a boulder-strewn river to the High Falls of the Cheat, crossing a bridge barely wider than the train, rumbling through an 1,800-foot tunnel and passing an abandoned rail bridge to nowhere.
Sometimes, riders get off at Woodrow and walk back to Elkins, fishing 5 miles of river. Other riders reach the falls — where the 35-degree curve is too sharp for the Flyer — and board the motor-driven Cheat Mountain Salamander, a "rail bus" without a locomotive, for a second journey.
Engineer Bob Robinson of Parkersburg says the operation couldn't survive if it had to pay $70,000 salaries, so most of the crew donate their skills.
"I treat this as a way to volunteer and allow Grandpa to take the kids out for a train ride," he says. "Some people go out and build houses and do other things. This is my way."
Bernadette and David Wilson of North Weymouth, Mass., discovered the Flyer when a timeshare swap landed them in nearby Canaan Valley. With David recovering from leg surgery, it seemed an ideal adventure.
"This is a slow, slow train," Bernadette says. "Some people don't like that. You have to want to have a relaxing trip and take your time."
But Howard Payne, the Flyer's announcer, says that's just what folks are starting to do — slow down.
"You can get there in a hurry if you want to," he says, "but why do it then?"
