Railroad on Bridge in The Sunny Isle Got Accidentaly Bulldozed

Same, and can't connect others either. What gives? 

I had same problem and I uninstalled and reinstalled the game twice and it is now fixed and working properly 

I cannot connect railroad bridges in Sunny Isles. Uninstall and reinstall no help. From looks of your pic I do not see connection. Red blockers seem to be problem 

Yes red blockers are there but it is connected and have no idea why they are, my trains run through them

I have same problem. No railroad on the bridge and no way to add.  

Sadly I have the same problem. Mistakenly bulldozed the railroad tracks on the bridge as well in the Green Valley region. Did anyone of you find a solution yet? 

Hopefully the next upgrade will fix this problem we all seem to have in Frosty Fjords with the trains. 

Same problem here at frosty. Demonstrated it trying to get rid of red blockers which was preventing me from extending a road.

Same problem here at frosty Fjords. I uninstalled and reinstalled the game few  times but can not fix the problem.
