The One-Click-Passenger was replaced with One-Click-Unload (abbreviated: OCU) with the 5 Dec 2016 Game Update.
OCU is now available with level 16 for 180 or
with level 35 for 90,000 ; 105,000 ; 105,000 .

At one point, Pixel Federation offered One-Click-Cargo, One-Click-Passenger, and One-Click-Mail for free to new players who played the game via the TrainStation Portal. However, they realized that this made the game unbalanced, and they removed this incentive. Pixel still promote the Portal as the preferred method of playing the game, using Portal-only content as incentives.
