At entry, to static conductor

This practice, previously more common in some South American cities, usually locates a seated conductor at an on-board entry barrier towards the rear of the vehicle, with all passengers boarding through a rear door and exiting alongside the driver at the front of the vehicle or through a middle door. It is applicable usually to single-decked vehicles.

The layout of the passenger saloon to suit this practice requires a rear assembly area, which reduces the carrying capacity of the vehicle, and barriers to channel passengers past the conductor. These barriers act to restrict access to and egress from the extreme rear of the passenger saloon, and make this area unsuitable for short-distance riders.

The objective is that all passengers pay the conductor at the barrier or are checked for other valid travel documents. Congestion of passengers in the rear assembly area can occur when the numbers boarding is high and the flow passing the conductor is slow. The objective is for the conductor to have the assembly area clear for the passengers boarding at the next stop.

This practice helps to improve stop dwell time, but at busy periods, congestion may occur in the area after the barrier which can then slow the movement of passengers from the rear assembly area. Short-distance passengers are particularly inconvenienced by this process as they need sufficient time to pass the conductor and then to reach an exit door.

With this practice, the seated conductors cannot easily identify those passengers that are travelling beyond the distance that their ticket entitled them to, and the driver cannot easily assist in that process.
