Train Derailing and Chase Map (REVAMPED) for Teardown

Using the old TDAC Map, I edited and added a couple of things:

• realistic ground at the end of the line, along with a few more props
• destructible houses placed towards the end
• longer, faster, and stronger train
• added a river and two destructible bridges (one with realistic guardrails)
• added a ladder at the construction zone to get up onto the bridge
• Lots more vehicles
• Flat car hauling excavators
• train couplers no longer compress
• apartment complex near the bridge
