I need a way to sell my train items

A level 19 city can't use pickaxes and lamps (I can only use screws and railwayman's hats). I also receive pickaxes and lamps as rewards in the mayor's pass. They occupy the warehouse, but I can't use them anywhere.

I reported the issue to support, and after three attempts, I received a response that they were analyzing the problem and would be working on it. This was a few days ago.

Yes upgrade housing and also do cargo, airport and export deliveries. Alternatively don’t buy them coz that’s the only way up you get them

Or upgrade houses, remember it's alleged to be a building game 🤣 

The only option for me is to use ships for them. Many times you need train items to send a ship
