Train Foundry

Build complete trains from blueprint templates — no more placing locomotives and
wagons by hand.

A large foundry building sits on the end of one of your rail lines. Import a
train blueprint into it, queue it, and the foundry assembles the whole train and
sends it off onto your network on its own — with the right composition,
orientation, colors, fuel, schedule, train group and blueprint parameters.

How it works

• Place it on a rail. The foundry's exit gate goes on the end of an
  east-west rail line (one straight rail under the western apron). The rest of
  the building can sit anywhere buildable.
• Import blueprints. Open the foundry and drop a train blueprint into its
  library (from your inventory or the blueprint library). Blueprints must contain
  only the train (rails and signals under it are fine).
• Queue trains. Click a template to queue it; blueprint parameters are asked
  once. Trains are built one after another.
• Feed the parts. Each build pulls its locomotives, wagons and fuel from the
  foundry's internal chest — fill it by hand or with inserters. Missing parts are
  shown in red, available ones in green.
• Off it goes. Once built and the track is clear, the train drives away with
  its schedule, group and fuel already set.

Extras

• Circuit network. Wire the foundry's connector to broadcast either the
  internal stock contents or the components it still needs.
• Remote control. A shortcut-bar button (or CTRL+ALT+F) opens the foundry's
  window from anywhere — no need to walk to it. One foundry per planet.
• Compatible with vanilla, Space Age and Nullius.
