In case you have purchased the Resend extension from your shop, you can now utilize the following features which are included in the Resend extension.
Friend IT Unload Button - Unload all International Trains from friends on your station with one click.

From now on, there is no need to spend several hours unloading your International trains one by one, you can utilize this feature! It works just like the resend button, except it will unload all of your International trains at your station. This button can be located in front of the International trains which will arrive to your station.
One Click Bonus Collection - Collect bonuses from destinations and contract partners with one click.

The bonus for unloading your Local and International trains can now be collected without ever leaving your own station, thanks to the Collect button which will appear right next to the bonus destination marker. It is up to you whether you would like to visit this bonus destination and see its beauty, or you can just collect your bonus right away.
Faster Trains on your Station - Receive and dispatch trains on your station much faster.
The Trains which will arrive at your own station are now much faster. We want to make the gaming experience seamless and we realize that waiting for Steamers might consume quite a bit time when you are running a high volume Local train fleet.
