It is unlocked at reputation level 4.
The personal train changes as the player upgrades it:
Repairing the train
Repairing the train costs 13,000 coin and takes 6 hours.
Picking up visitors
Players can tap the train to see who among their neighbors has visitors waiting at their train station. Tapping a neighbor's icon sends the personal train into this neighbor's town.
Players can then tap any visitor standing at the neighbor's station to send them to their own towns. Once the visitor has gotten off the train it goes into maintenance time for six hours.
If no visitor is selected, the personal train returns to the player's station and may be sent out to another neighbor's town.
If a player picks up less passengers than their maximum allowed at a single town, the train will still go into "maintenance time" once it arrives back at their town; they cannot send it back out to pick up passengers at other towns.
One reputation point is given for each picked-up visitor: the point goes to the player whose visitor was picked up.
Points are given even if the visitor is not served in its destination town.
Players can upgrade their personal train either to increase its capacity or to decrease its maintenance time. Upgrades require refine coal, iron bars and alternatively silver bars, gold bars or platinum bars (see the table below).
If the player chooses to increase the capacity, then the train can seat one more visitor than before, to a maximum of 10 visitors.
If the player chooses the maintenance option, the train's maintenance time decreases by 30 minutes, to a minimum of 1 hour and 30 minutes.
Upgrading the personal train upgrades its level, to a maximum level of 19.
