Train Network

Plan, simulate, optimize rail.

Place cities, draw the lines, then run the network and watch passengers, congestion and costs respond in real time. Beat the scenarios and refine your best layout — rail planning you can actually see.

Deterministic engine 10 scenarios 4 live heatmaps All on-device
The loop

Four moves, one railway

Everything happens on one map. Build, run, read the numbers, build again — the whole network reacts to every corridor you lay.

STEP 01 🧭

Plan the network

Drop stations, draw corridors and connect cities into a working railway. Every link you lay reshapes how the map flows.

STEP 02 🚄

Simulate the flow

Run the deterministic engine and watch trains and passengers move in real time. Load, congestion and trip times update on every change.

STEP 03 📊

Optimize with data

Read live analytics — efficiency, coverage, cost and heatmaps — then upgrade tracks and reroute demand to raise the grade.

STEP 04 🎯

Take on scenarios

Ten challenges with their own maps, budgets and targets. Beat them, save your best networks, and unlock milestones as you go.

Inside the sandbox

A simulator that answers back

Real speeds, real capacities, real operating costs. Nothing is decoration — every number on screen comes out of the same engine that moves the trains.

🚄

Three service classes

Local, Express and High-Speed each carry their own cruising speed, seat capacity, fare and running cost. Pick the wrong one for a leg and the ledger tells you.

Local · 70 km/h Express · 135 High-Speed · 265
🚉

Stations with character

Hubs pull heavy all-day interchange, suburbs spike at peak, resorts surge on weekends. Platforms cap what a station can turn over — add more, or watch it choke.

🛠️

Upgrade the corridor

Double a track for roughly 1.85× capacity and fewer conflicts, or keep it single and lean. Congestion is graded live from idle to overloaded, corridor by corridor.

Four live heatmaps

Passenger density, busiest stations, spare bandwidth and route usage — switch between them and the weak link in your network shows itself immediately.

Smart corridor hints

The planner watches unmet demand and suggests the links worth building next. Tap once to lay the corridor, then re-run and see what it bought you.

Projects & snapshots

Save any layout as a project, capture snapshots before a risky rebuild, and come back to compare. Badges track the milestones you hit along the way.

Train Network is an offline planning sandbox. Every figure on screen is computed on your device — no account, no sign-in, no network required.

Analytics tab

Every run, graded and charted

On-time performance, coverage, directness, revenue against operating cost, station load, route popularity — the whole picture, updated the moment the sim finishes.

Ten challenges

Own map. Own budget. Own disaster.

Each scenario hands you a starting map, a construction budget and an efficiency target — plus a twist that breaks the obvious answer.
