Wait, there are no bridges over or tunnels under the rail tracks in a big city? What kind of twisted planning is this?

Wait, there are no bridges over or tunnels under the rail tracks in a big city? What kind of twisted planning is this?
- michaelt 2y agoPresumably, planning that took place 100 years ago when a train would pass by in 60 seconds or so. Once you've built the rails, built the roads, sold off the land nearby and constructed buildings, adding a bridge later can be difficult. If your bridge is 22 feet high, and the approach ramps have a 6% slope, each approach ramp will be 360 feet long.
- mind-blight 2y agoThere is a pedestrian bridge, but the nearest for vehicles is a couple of miles away. There are 3 roads connecting these two parts of the city, but I've had a train cut off all 3, then stop. It must have been there for around an hour. There are often alternatives, but they add 10-30 minutes depending on where you're at. That's really bad in an emergency situation
