QUICK ANSWER
Measure train speed on the map, multiply by estimated shell flight time, place the aim point that distance ahead on the route, then fire early enough for both paths to meet.
Operator briefing
Iron Road is a timing problem, not a fixed-coordinate puzzle. Measure motion, predict the train’s future position at impact time, and maintain a separate plan for the static phases that follow.
Use the procedure below as a decision sequence, not as a substitute for the live mission order. Random coordinates, balance values, and mod compatibility can change; stable facts and version-sensitive evidence are labelled separately.
Field procedure
- 01
Observe the train over a measured interval to estimate map speed.
- 02
Obtain flight time for the selected charge and distance from a verified source.
- 03
Project the train forward by speed × flight time along its actual route.
- 04
Build the shot to that intercept point and fire when the timing condition is met.
- 05
After the intercept phase, switch to fresh cards for bunkers or later objectives instead of reusing train data.
Checks before you commit
- Never copy another run’s timestamp as a universal answer.
- Small speed errors grow during long flight times.
- `All Clear` and `Crowned in Brass` confirm the mission and full-medal objective.
When the live game conflicts with this page, keep the live observation, game build, and source date. That evidence becomes the next revision instead of being silently forced into an old answer.
