After entering the gondola station you will be allowed to interact with Veni, Vidi, Vigor! and Dollar Bill machines located on the left side. You'll soon take part in an intensive battle with a squad of policemen, so if you have enough money (and if you're interested) you should upgrade your vigors and replenish health and salt. There's also a Vantage Point #10 to your right (the only one in this chapter).
Once you're ready use one of the side corridors to get to the main hall of the gondola station. You can make this new battle a lot easier by immediately taking control over a turret located behind the angel statue in the middle of the hall. Use the fact that enemies are distracted by turret attacks. The policemen may even destroy the turret so you also won't have to worry about it. Another good idea is to stun enemies using the Murder of Crows vigor when they're engaged in a firefight with the turret, allowing you to quickly and painlessly deal with them. Once the battle is over explore the main hall and side corridors, searching for ammunition, medkits and bottles of salt.
Use the stairs to get to the ticket office. There are rooms on both sides of the office and they have a lot of loot. The room to your right contains salts, a machine gun and some silver.
The room to your left on the other hand contains a safe with a lot of coins found around it. Examine the rest of the furniture and then go back to the ticket office.
In order to get to the middle ticket stand you must use a nearby door and turn right after reaching a new corridor. The door to the stand can be found just around the corner, near vending machines. The stand contains mostly money.
