Samuelsville Transit Authority Headquarters, Terminal & Central Garage; catty-cornered across the street from the Union Station complex. (Samuelsville, Ind.)
I. The Main Terminal: Art Deco & Art Moderne (1935/1948; HQ expansion in early 1950)
The terminal is a three-story vertical transit hub. The 1935 core features Mesker steel windows, while the 1948 & '50 expansions utilized reinforced concrete to bypass post-war steel shortages, finished with modern aluminum glazing frames.
1. Portals and Vertical Transport
Entry is gained through high-traffic Ellison Bronze Co. balanced doors, engineered to open with minimal effort against the wind tunnels created by departing buses. Inside, vertical movement is handled by Otis bottom-drive traction elevators. These units house the machine gear in the basement to isolate vibration from the waiting areas, featuring the tactile Classic Black Buttons synonymous with Samuelsville’s public buildings.
2. The Electrical and Lighting Grid
The terminal is a total Westinghouse environment.
• Illumination: The passenger concourse uses decorative Westinghouse fixtures, while the loading bays are lit by high-intensity Holophane mercury vapor units.
• Safety Signage: The exit signs are heavy-duty Kirlin Co. units from Detroit. In the loading bays, these are protected by steel wire guards to prevent damage from luggage carts or maintenance equipment.
• Switchgear: All circuits terminate in Westinghouse panels utilizing Harvey Hubbell wiring devices, ensuring industrial-grade grounding for the massive transient load.
3. Thermal and Fluid Dynamics
• HVAC: The air is tempered by B.F. Sturtevant equipment (Westinghouse’s post-war acquisition), controlled by high-precision Powers Regulator Co. pneumatic thermostats.
• The Cooling Loop: The 1935 section originally relied on a Marley Co. “wooden Aquatower”, a rare Redwood-framed cooling tower. In 1948, a galvanized steel Marley unit was added to handle the increased load of the expansion.
• Boiler Plant: A massive Burnham cast-iron boiler provides steam, while **Swartwout “Airjector”**roof ventilators ensure constant air exchange in the exhaust-heavy environment.
• Pumping: The terminal relies on Myers Co. pumps to manage the complex’s fluid requirements through a network of copper supply and cast-iron drain lines.
II. The Central Garage: Industrial Might (1936/1949/1955)
The garage is the “Workhorse” of the STA, designed for the heavy maintenance of the “New Look” fleet. The architecture is defined by Truscon steel windows and massive Kinnear Co. roll-up doors. Originally manual, these doors were motorized during the 1949 expansion to accommodate faster fleet turnarounds.
1. Specialized Maintenance Infrastructure
• Spencer Turbine “Bus-Vac”: A massive industrial-grade Spencer Central Vacuum system is the garage’s primary cleaning tool. High-suction overhead drops allow crews to “strip-clean” bus interiors in minutes. The terminal features a similar system to that of the Central Library. Another feature is a special relay which disables the system during a fire alarm activation.
• L.J. Wing Heaters: To combat the constant opening of the Kinnear doors, the garage uses L.J. Wing “revolving” vertical discharge heaters. These units rotate 360 degrees, distributing a “curtain” of hot air that prevents the diesel engines from cold-soaking.
• Safety: Given the presence of fuel vapors, the electrical system uses Westinghouse explosion-proof wiring devices. Throughout the service bays, Speakman Co. emergency showers stand ready for accidental chemical exposure.
2. The Office and Cafeteria Wing
Adjacent to the bays, this wing serves as the human heart of the STA. It houses the medical suite and locker rooms, featuring Kohler industrial plumbing and Powers Regulator Co. shower valves to ensure consistent water temperature for drivers coming off long shifts.
III. Integrated Life Safety and Communication
The STA is electronically tethered to Union Station, creating a unified “Transit Time Zone.”
1. The IBM/Autocall Fire Logic
The fire alarm system is an IBM coded network with a specific hierarchy of notification:
• The Terminal: Uses Autocall NYSP coded pulls (semi-flush; surface in loading bays) and 10-inch single-stroke “baseball visor” bells. The visor design directs the sound downward toward the commuters.
• The Garage: Uses surface-mounted IBM 4250 non-coded break-glass stations. The signals are IBM 4030-1/2 horn-lights, capable of cutting through the roar of revving engines.
• Detection: The 1948 expansion introduced Fenwal “DETECT-A-FYRE” rate-compensation heat sensors, designed to trigger the alarm only when the ambient temperature exceeds a set point, preventing false alarms from bus exhaust.
• Suppression: The garage was built with a Grinnell sprinkler system tied into the IBM 4200 via a Potter flow switch; also includes a “Tamper Switch” on the main O.S.&Y. (Outside Screw and Yoke) valve. If a mechanic forgets to reopen it after maintenance, the panel immediately triggers a remote “Trouble” buzzer at the HQ.
2. Timing and Pneumatics
• Clock System: All clocks are slave units to the IBM Master Clock at Union Station. The garage features double-sided hallway clocks to ensure mechanics and dispatchers are perfectly synchronized.
• Lamson Tubes: A Lamson pneumatic tube system connects the ticket booths in the terminal to the central counting room and the garage dispatch office, allowing for the rapid transit of paper manifests and cash bags.
3. RCA “Victor Deluxe” Audio
Communication is handled by an RCA Victor Deluxe system.
• Terminal: MI-6294 wall speakers provide high-fidelity announcements in the waiting rooms.
• Loading Bays: Rugged MI-4420 speakers are used to withstand the humidity and fumes.
• Expansion: The 1948 & ‘50 wings use the then-modern MI-6104/6 molded plastic cabinets, a signature of post-war RCA design.
2026: The AI “Predictive Nexus”
The AI Data Center at Union Station uses the terminal and garage as its primary data inputs for city-wide logistics:
• Pneumatic Monitoring: The AI monitors the “Air Pulse” of the Lamson tubes and the Spencer Turbine vacuum. If the static pressure drops, the AI identifies the leak before it affects the Burnham boiler’s efficiency.
• Thermal Balancing: By cross-referencing Powers Regulator data with the L.J. Wing heater activity, the AI optimizes the steam loop between the terminal and garage, saving 15% in annual fuel costs.
• Safety Coordination: The AI integrates the Fenwal heat sensors with the Kinnear door controllers. In a fire event, the AI automatically opens the bays to evacuate smoke while silencing the RCA PA to provide clear, synthesized evacuation instructions.
STA history:
I. The Streetcar Era & The Great Transition (1890–1946)
In the early 20th century, Samuelsville was a “Trolley Town.” The KI&S Railroad-backed streetcar lines formed the city’s skeletal structure, powered by a massive Westinghouse DC substation.
• 1935: The First Breaking Point: As the Great Depression deepened, the STA faced its first massive labor strike. Workers protested for living wages and the formal recognition of the Amalgamated Transit Union. The city was paralyzed for three weeks, leading to the construction of the 1935 Art Deco Terminal as a peace offering to the public to modernize service.
• The Diesel Pivot: Recognizing the flexibility of rubber-tired vehicles, the STA began integrating buses in the mid-30s.
• 1946: The Final Run: Following the end of WWII and the lift of wartime fuel rationing, the streetcars were deemed obsolete. In a massive civic undertaking, the rails were ripped up and the rolling stock was melted down into scrap metal (though a a few cars made it into preservation), shipped across the Atlantic to aid in the post-war reconstruction of European rail networks, as well as the US’s own network.
II. Post-War Growth and The First Decline (1947–1972)
The 1948 terminal expansion signaled a new era of diesel dominance. However, the rise of the American automobile soon threatened the STA’s viability.
• 1962: The Automobile Shift: As the suburban sprawl of the 1950s took hold, ridership began a steady decline. The “Glass Box” neighborhood libraries and new shopping centers were increasingly accessed by private cars, leaving the STA to serve primarily the industrial core.
• Infrastructure Aging: During this era, the Burnham boilers at the central garage and the IBMclock systems were the only things keeping the aging fleet on a reliable schedule.
III. Crisis, Resurgence, and Industrial Decay (1973–1989)
The 1970s brought a volatile “boom and bust” cycle to the STA.
• 1973: The Oil Resurgence: The OPEC oil embargo forced Samuelsville residents back onto the bus. Ridership spiked overnight, prompting the 1973 mall conversion at Union Station to better serve commuters.
• 1978: The Industrial Strike: Just as the city’s industrial base began to flicker, the STA was hit by its second massive strike. Amidst rising inflation, drivers walked out, leaving industrial and railroad workers stranded. The strike was settled, but at a high cost to the city’s dwindling tax base.
• 1984: The Second Wave: As the primary manufacturing plants began to close, the tax-funded subsidies for the STA evaporated. Ridership plummeted as the working-class population either moved away or could no longer afford the fare.
IV. The Modern Era: Light Rail & Digital Shifts (1990–Present)
The 1990s saw an attempt to return to the city’s roots with a move back toward rail.
• 1992: The Light Rail Entrance: Amidst a new wave of environmental awareness, the STA opened its first light rail line, utilizing two tracks at Union Station. This was supported by a new GE electrical backbone and integrated into the existing IBM timing network.
• 2008: The Great Recession: A smaller, bitter strike occurred as the STA attempted to cut routes to survive the global financial collapse.
• 2020: The COVID Blow: The pandemic nearly bankrupted the STA. With the Union Stationoffice tower abandoned and remote work becoming the norm, revenue fell by 70%.
• 2025: The Rider Safety Strike: In a fourth major labor action, operators walked out to protest “unruly riders” and a lack of security. This led to the 2026 integration of the AI Data Center at Union Station, which now uses data from onboard cameras.
The 2026 AI Oversight
Today, the Gemini 3 Flash AI at Union Station manages the recovery:
• The “Safety Shield”: Following the 2025 strike, the AI uses the onboard cameras and speakers to monitor cabin stress levels, automatically alerting transit police if a conflict is detected.
• Optimized Routing: To counter the post-COVID revenue loss, the AI uses IBM-synced data to run “On-Demand” shuttles during off-peak hours, keeping the Wing heaters at the garage efficient.
