Tunnel of the Fredericksburg & Northern Railway
Comfort, Kendall County, Texas
Marker Inscription
In 1913 area residents raised money to build a railroad linking Fredericksburg to San Antonio. The 920-foot tunnel beneath this hill increased the cost by $134,000 and required five months of hard labor. It opened a faster trade route for area merchants and farmers. Each time passenger trains entered the tunnel, small rocks, loosened by engine exhaust, were removed from the track and the windows closed to keep out coal smoke. The railroad operated until 1942 when the trackage was sold for scrap. (1978)

The Story
In 1913 residents of the Texas Hill Country raised their own money to connect Fredericksburg to San Antonio by rail, and the 920-foot tunnel bored beneath this hill was the project's costliest, most grueling stretch. Passengers learned to close their windows against coal smoke as trains rumbled through, while crews cleared rock shaken loose by engine exhaust. The line carried farmers' and merchants' goods until 1942, when its track was pulled up and sold for scrap.
Why it matters
The tunnel captures the ambition of rural communities that financed their own railroads to escape isolation, and its scrapping marks the mid-century decline of branch-line rail across America.
The story behind this marker
AI contextThe era
In the early 1900s, the Texas Hill Country was beautiful but isolated. The German settlers who founded Fredericksburg in the 1840s had built a thriving farming and merchant town, but getting crops and goods to a big market like San Antonio meant slow, rough travel by wagon over hilly roads.
All over America, the railroad was the dividing line between towns that grew and towns that fell behind. A community with a rail connection could ship its harvest fast and bring manufactured goods in cheaply. A town without one risked being left behind. So many rural places tried to raise the money to build their own lines.
This was the Progressive Era, a time of civic ambition and faith in improvement. When Hill Country residents decided in 1913 to build a railroad of their own to San Antonio, they were acting on the same belief that drove small towns across the country: that modern transportation was the way to prosperity.
People & events
What stands out about this railroad is who paid for it. The line wasn't pushed in by a distant railroad baron. Local residents raised the money themselves, betting their own savings that a rail link to San Antonio would pay off for their farms and businesses.
The hill above this spot was a serious obstacle. The builders cut a 920-foot tunnel through it, and the marker records the price: $134,000 in added cost and five months of hard labor. For a community-funded project, that was a huge commitment, and it shows how much local people wanted the railroad finished.
Once trains were running, the tunnel had its own routines. Engine exhaust shook small rocks loose from the tunnel walls, so crews had to clear them from the track. Passengers learned to shut their windows before each trip through, or the cars filled with coal smoke. For about three decades the line carried merchants' goods and farmers' produce. Then in 1942 it shut down, and the track was sold for scrap.
Its place in the American story
The Fredericksburg line is a small example of one of the biggest forces in American history: the railroad, and the hopes riding on it. Across the country, towns large and small organized, borrowed and sacrificed to get connected, knowing their economic survival could depend on it.
Its short life shows the next chapter too. In the decades after this line opened, cars, trucks and paved highways gave rural Americans new ways to move people and goods. Many small branch lines lost traffic and closed, and their rails were pulled up. This railroad's end in 1942 fits that national pattern.
The timing of that end also points to a wider world. By 1942 the United States was fighting World War II, a period when metal was valuable. The scrapping of lines like this one marked the end of an era for rural rail, even as the steel went on to other uses.
If you visit
The hill that once forced crews into five months of digging is still here, and the tunnel beneath it still exists. It's hard not to picture a steam train disappearing into the dark, windows slammed shut and smoke pouring from the portal.
Today the old tunnel has a surprising second life as home to a large colony of bats, and the site is protected by the state. The tunnel itself is closed to people to protect the colony, so check current visiting rules before you go and respect any posted limits. If your trip lines up with the season and time of day when the bats come out, their evening flight can be unforgettable.
The tunnel is a natural stop on a Hill Country drive between the Comfort area and Fredericksburg. Pair it with Fredericksburg's German heritage and the region's small towns, and you'll get a real sense of the isolated, determined communities that once went to such lengths to get a railroad.

Ingenhuett-Faust Hotel
Comfort, TX
The oldest wing of this Comfort inn, trimmed with jig-cut brackets and a balustrade, went up in 1880, with an addition following in 1894—seven years after the railroad reached town. Both sections were designed by prominent San Antonio architect Alfred Giles. The Ingenhuett family ran the hotel into the 1900s before Louis and Matilda Faust took over from 1909 to 1946.
Beitel Lumberyard
Kerrville, TX
When the San Antonio & Aransas Pass Railroad made Kerrville its last stop, San Antonio lumberman Frank J. Beitel bought land here in 1889 to open a lumberyard, betting on the county's timber and coming growth. The business thrived, expanding into a warehouse, retail building, and lumber shed, and gained its own rail spur for loading goods after the town's depot was rebuilt in the 1910s. For more than a century the yard supplied the materials that built Kerrville.
Engel Family
Luckenbach, TX
The Rev. August Engel, a circuit-riding Methodist preacher who emigrated from Germany in 1846, and his descendants shaped the tiny Hill Country community that became Luckenbach. When a post office opened in an Engel home in 1886, daughter Minna — married to C.A. Luckenbach — was asked to name it and chose the family name. Around the store, post office, blacksmith shop, cotton gin, saloon, and dance hall, generations of Engels served as postmasters until the office finally closed in 1971.
The Pinta Trail
Fredericksburg, TX
Long before wagon wheels cut its ruts, the Pinta Trail began as a path worn by nomadic Plains peoples across the Texas Hill Country, linking San Antonio de Béxar with the San Sabá River country near present Menard. Spanish and Mexican expeditions borrowed its general course, and in 1845 German immigrant surveyors improved part of it into a wagon road. After the 1849 California gold rush, U.S. military companies pressed it into service scouting new routes west, until the railroads of the late 19th and early 20th centuries made the old trace obsolete.
