Backing out of the roundhouse

JAMESTOWN, Calif.--For 115 years, this small Gold Country town has been home to a steam locomotive repair and maintenance facility loved by tourists and Hollywood alike.

Featured in more than 200 movies and TV shows, and a favorite of train aficionados, Railtown 1897 State Historic Park here offers the opportunity to see how steam locomotives have worked for more than a century -- and even to take a ride in a passenger car pulled by one of the venerable engines.

As part of Road Trip 2012, CNET reporter Daniel Terdiman visited Railtown and got an up-close look at how hostlers -- the hard-working people that move steam locomotives around railyards -- handle the intense heat of their job.

No. 3

Railtown maintains three steam locomotives -- No. 3, which was used to help build the Sierra Railway in 1897, and which is seen here, and Nos. 28 and 34, which were purchased for the railway in the 1920s.

Putting oil on the rag

Stephanie Tadlock, a volunteer hostler at Railtown, is a qualified fireman, meaning she has responsibility for starting, and maintaining the fire that generates the steam used to power the locomotive.

Here, Tadlock pours oil on a rag that she will light and toss into the locomotive's firebox.

Putting the rag in the firebox

After lighting the rag on fire, Tadlock prepares to toss it into the firebox, where a mixture of oil and air keeps a roaring fire burning in order to move the locomotive.

Fire gets going

After tossing in the burning rag and working to find the right mixture of oil and air, Tadlock's fire burns, slowly building up pressure.

Opening atomizer valve

Tadlock adjusts a knob to open up what is called the atomizer valve, which is used to control the mixture of oil and air inside the firebox.

Economy haze

As Tadlock works on finding the right mixture of oil and air, smoke begins to rise out of the locomotive's smokestack. Because it's not black smoke, this is called an "economy haze," Tadlock explained.

Hydrostatic lubricator

A truly steampunk-looking device, this is a hydrostatic lubricator, which provides lubricating oil to the locomotive's cylinders and its compressor.

Gauges

These three gauges provide the fireman and the engineer with information they need in order to know whether the locomotive is ready to roll. The large gauge on the bottom shows how much pressure has built up in the boiler, while the top two provide similar information about the brakes.

Tenders

These are the locomotive's tenders. On the right side -- and also out of the frame on the left -- is a round section carrying all the locomotive's water. And in the center is the container full of oil.

Fireman's manifold

This is the fireman's manifold, a set of valves used to adjust the fuel and air mixture for the locomotive's boiler.

Johnson bar

This is the "Johnson Bar," or reverser. It is used to determine the direction the locomotive moves. If pulled toward the foreground, the locomotive will move backwards. If put towards the background, it will move forward.

Letting out water

Dave Tadlock adjusts the amount of water inside the hydrostatic lubricator by opening a valve and letting it blow out.

Steam and No. 3

Steam billows out of the boiler of Railtown's No. 3 locomotive, its oldest.

319

Dave Tadlock points a device at the firebox that is used to instantly determine temperature. Inside the locomotive's cab, it can easily be 140 or 150 degrees Fahrenheit. The outer metal wall of the firebox is at 319 degrees in this picture.

Brakes

These two brass handles are used to control the locomotive's brakes. On the right is the engine brake, which is used to stop only the engine. On the left is the train brake, which stops the entire train.

On turntable

Outside the roundhouse is the Railtown turntable, which is used to determine which track the locomotives will head out on, or whether they'll come back into the shed.

Hanging off the side

As the locomotive moves down the track, Stephanie Tadlock hangs off the side, ready to jump off and provide signals to the engineer, or to adjust the track.

Sand valve

This valve is used to put sand on the tracks if they are too wet or slippery, a condition that can cause the train to slide backwards on an incline.
