I've been wanting to do this for ages.
This is my interpretation of the Sky Bandit passenger wagon based on this: www.derpibooru.org/106335?scop…
Now for the head cannons:
The Sky Bandit Stages Air-Tram is a medium lift flight assisted pegasus pulled passenger wagon.
It uses a series of thrusters powered by an array of Spark Cells to provide stability and help the pilot lift the weight.
The harness is linked to an on-board control terminal that reads the pilot's body and wing movements to control the output of the ventral and rear thrusters.
Manufacturer: Sky Bandit Stages
Operator: Fetlock Transport Company
Seats: 30 with an additional 10 standing
Flight time: 8 hours, effectively indefinite with use of recharging stations
