Block System

^ Or like SM:ROS under normal operating conditions?

What the engineers will more than likely do is set the base of the lift as part of the lift block. When a train rolls down the hill it will stop before entering the block before it. The next train would not be permited to enter the lift block (including the base area) unless the train drops off of the lift and clears the lift block.

Unlike drive tires, eddy brakes and the dynamic braking used with the LSM are unaffected by water.

After rolling backwards down the lift drive tires will most likely located at the bottom in the default up position, similar to the ones at the launch area for TTD. So when the train hits the tires, it skids to a stop.

Number one rule for any blocking system is that NO train can hit another train under any circumstance, emergency or not, all blocking systems are built around this rule.

Block systems on all coasters operate under the same principles. It's not difficult to understand if you just remember, as Gomez stated, two trains can not collide. It's even more simple on coasters like MF where there are no mid-course brake runs. Just remember that the train can't leave the lift until the next open block(brake run, in this case) is vacant.
