Express Trains are game-controlled trains that appear at your station and award small amounts of materials 
, gold 
, and/or experience 
. An arriving/waiting Express Train is indicated by blue signal lights.
Local Express Trains
If you are logged into the game, and you have an empty rail at your station for 10 consecutive minutes, an Express Train will appear. As long as one rail remains clear, another Express Train will arrive until all rails are filled. Express Trains can be identified by their blue outline.
Express Trains will now wait in your station forever until you unload its wagons. This was changed in the first half of 2017, the exact date is unknown.
Express Trains are randomly generated by the game and can be matching sets or a mix of different locos/wagons. They are level-dependent and will become more advanced as the player levels. Occasionally, and for a limited time, PixelFederation will increase the chances of seeing rare locomotives as Express Trains to help players fill out their Museum.
NOTE: Hyperloop Express Trains only deliver XP.
Redirecting Express Trains
As the game progresses, there may be a large volume of trains arriving at the player's station which can get hard to manage. At level 140, the Special 
building Train Yard Tower can be purchased. This building will divert all local Express Trains to the station it is placed on. Having it at any other player station will help clean up and organize the main station rails and also increase the number of incoming Express Trains, because there are always free rails until filled up.
Whistles
Whistles are used to immediately divert an Express Train to the player's station. They can be used at any time a rail is open at their station. The Whistle button will display the number of whistles the player has to use. Added with the 31 Mar 2011 Game Update.
Whistles are awarded from a few sources:
- Completing Contracts
- Completing Achievements
- Collecting Local Trains
- Playing the Train Ride mini-game
- Daily play gift
Neighbour Express Trains
Every 23.5 hours, the player can also collect Express Trains from their neighbor's stations. See Neighbors.
