SimCity Buildit: Bug - Possibility of demolishing the tracks on the bridge

In SimCity: Buildit from the update adding the tracks and trains to the game there is a possibility to demolish/delete the tracks on the bridges (outside the city borders). It's only possible in the Sunny Isles region on the bridges connecting the islands.

The problem is that once these railway tracks are removed, there is no way to rebuild them. The affected bridge sections are located outside the playable city boundaries, so the game does not allow new tracks to be placed there.

As a result, the railway network becomes permanently disconnected, making it impossible for trains to travel between some parts of the region. This can severely impact gameplay and progression related to the train system.

Steps to reproduce:

1. Open the Sunny Isles region.

2. Locate a railway bridge connecting two islands.

3. Enter demolition mode and remove the railway track on the bridge.

4. Attempt to rebuild the track.

Expected result: The game should either prevent demolition of essential railway tracks outside city boundaries or allow players to rebuild them.

Actual result: The track can be demolished, but cannot be rebuilt because the bridge section is outside the buildable area.

I believe this is a bug and would appreciate if the development team could investigate and provide a fix.
