1886
Motor carriage
Cities are still shaped for horses and rails; the machine is a workshop experiment.
Infrastructure Workshop and a smooth street — not a highway network.
Arrow keys move eras. The infrastructure table follows the scrubber.
Five editorial eras per family. The last stop is not “best to buy”.
1913
Moving line
The chassis becomes a factory rhythm, and roads begin to follow the car.
Infrastructure Plant, fuel depot, paved arterial.
1956
Limited-access road
Highway geometry makes the automobile the default box between cities.
Infrastructure Grade-separated roads, service stations, suburbs.
1990s
Electronic chassis
Brakes, bags and engine maps become software problems.
Infrastructure Diagnostics, crash rules, electronics supply.
2010s
Plug and network
Energy moves from tank to battery plus a charging graph — a systems shift, not a buy signal.
Infrastructure Chargers, grid capacity, battery logistics.
1825
Iron timetable
Steam on iron; the timetable is the product.
Infrastructure Rail, coal, station clock.
1880s
Gauge politics
Networks argue over gauge, signals and who owns the clock.
Infrastructure Standard gauge, telegraph, workshops.
1964
Dedicated speed
Dedicated track beats sharing the line with freight.
Infrastructure New alignment, power, exclusive slots.
1970s
Urban electric
Metro and light rail return as city capacity, not nostalgia.
Infrastructure Tunnels, wire or third rail, fares.
2000s
Signal software
Capacity comes from moving blocks and control rooms, not only steel.
Infrastructure In-cab signalling, maintenance windows.
Sail age
Wind timetable
Routes follow wind and charts; duration is weather. No warship scoreboard.
Infrastructure Port, rope, chart.
1840s
Steam schedule
Coal bunkers buy a timetable the wind does not set.
Infrastructure Coaling stations, dry dock.
1956
The box
The container standardises the hold; the crane is the bottleneck.
Infrastructure Box, gantry, deep berth.
1970s
Draft scale
Bulk and tanker scale hit canal and port depth limits. Technical constraint, not a trophy.
Infrastructure Deep water, ballast rules, pilots.
2010s
Slow and dual-fuel
Efficiency rules reshape speed — a regulation story, not a shopping list.
Infrastructure Slow-steam slots, fuel spec, shore power.
1903
Fabric and wood
Short hops; the airframe is carpentry plus an engine. Civil experiment, not a combat score.
Infrastructure Field, shed, mechanic.
1930s
Metal schedule
All-metal airliners make passenger timetables plausible.
Infrastructure Runway, radio, weather office.
1950s
Jet stage
Jet engines shrink oceans into stages; runway length and noise jump. Systems fact, not glamour.
Infrastructure Long runway, ATC, kerosene.
1970
Wide cabin
Widebody geometry is an airport and tourism system, not a silhouette contest.
Infrastructure Terminal fingers, hubs, slots.
1980s
Fly-by-wire
Control laws sit between pilot and surface; software is structure.
Infrastructure Software certification, simulators, maintenance data.
1957
First orbit
A radio beep proves a stack can reach orbital speed.
Infrastructure Range, tracking, expendable stack.
1960s
Staged throwaway
Multi-stage rockets trade hardware for delta-v.
Infrastructure Pads, tank farms, downrange safety.
1981
Winged reuse try
An orbiter tries to land the craft; turnaround stays hard. Engineering lesson, not a product ad.
Infrastructure Runway, thermal protection, hangar.
2000s
Cargo contract
Station resupply becomes a contract, not only a flag program.
Infrastructure Docking standard, cargo spec, range.
2010s
Partial reuse
Booster recovery changes cost structure. Engineering, not a consumer product.
Infrastructure Landing zone, telemetry, refurbishment.
1817
Balance machine
Two wheels can be a personal machine.
Infrastructure Path and workshop.
1880s
Safety bicycle
Equal wheels and a chain make a city tool.
Infrastructure Smooth road, tire, repair shop.
1960s
Small engine
Mopeds share bicycle space before rules catch up.
Infrastructure Fuel, parking, noise rules.
2010s
Shared scooter
Dockless fleets are a battery and curb problem, not a gadget review.
Infrastructure Charging vans, curb space, geofence.
2020s
Lane politics
Cities argue over lanes, speed caps and where batteries live.
Infrastructure Protected lane, speed policy, battery rules.
What the era needed
Cards pair each stop with the network behind it — ports, gauges, pads, lanes. Not a spec sheet to shop.
