Off Limits

There are three versions. In the former one could choose between seven different types of barrier; Large, mobile, with small mobile tunnels, with large mobile tunnels, with four fixed tunnels, with intermittent tunnel, wall. The selector was inside the car, so only the maintainer could choose.

The second version was sold to Zaccaria; It is unclear whether TBM has also marketed some units. In this model the player can choose the barrier type with an external command. The types are six: compared to the first version, wall is missing.

The third version brings the TBM brand, has an external selector to choose the type of barrier, but has only four types: large mobile tunnels and intermittent tunnel have been removed.
