To commemorate the end of trolleybus operation, several events were held between 15 April 2018 and 30 November 2018.[7]

• Distance: 6.1 km
• Stations: 2 (the two terminals; there are no intermediate stations)
• Track: Single, with a passing area in the middle of the route
• Railway signalling: Counter checking and staff token.
• Travel time: 16 minutes[4][1]
• Current fleet (as of 2020): 15 Hino Blue Ribbon electric buses, built in 2019

During peak hours, multiple buses operate through the tunnel in convoys. As many as 10 buses can be operated in a single convoy if ridership is high. During the trolleybus era (at least its later years), the maximum number of trolleybuses in a convoy was seven, and that was the maximum number that the passing area in mid-tunnel was able to accommodate.[1]

The original fleet comprised six Mitsubishi Fuso trolleybuses with bodies by Osaka Sharyo Kogyo, built in 1964, numbered 101–106 (renumbered 111–116 in 1976). Additional vehicles built by the same manufacturers, to the same or very similar design, were acquired gradually—at a rate of about one new trolleybus per year—between 1966 and 1973, carrying fleet numbers 107–110 and 201–205 (renumbered 117–120 and 211–215 in 1976).[4] The first six trolleybuses had only one door, at the front, but a second door was added in 1976, in the center. The next four (117–120) also had only a single door, and retained this configuration. The 200-series vehicles came with two doors. They had longitudinal seating, whereas the 100-series vehicles had forward-facing seats.

All of the 1964–1973 vehicles were withdrawn from service in the early to mid-1990s and replaced by a new fleet of nine trolleybuses built by the same two manufacturers,[8] in 1993 and 1994, and numbered 301–309.[9] Another six of the same type were delivered later, by 1996, making the full new trolleybus fleet 15 vehicles numbered 301–315.[1] All had two-and-one seating (forward-facing seats in pairs on one side of the vehicle and single seats on the other).[1]

Of the previous fleet, the first six were scrapped, but all nine of the others were donated to Mexico City's Servicio de Transportes Eléctricos (STE),[9] for possible use there, arriving in Mexico City in 1994–1997, but they were never placed in service by STE.[10]
