Most revenue officers on the Metro, which connects Birmingham to Wolverhampton, were former conductors who have been retrained for revenue protection duties, the transport provider added.
Their role includes ensuring ticket checks take place throughout the day to help prevent fare evasion, alongside issuing penalty fares where necessary.
“At busy times, it has sometimes been difficult for conductors to cover an entire tram between stops, and we know that the vast majority of customers don’t like to see some people travelling without paying their way,” said Michael Reading-Skilton, Metro’s head of commercial and customer experience.
“Our revenue officers will now be out on Metro services to help customers understand the new ticketing process and make sure everyone is travelling with a valid ticket.”
The number of ticket machines that accept card and cash at tram stops has increased, with tickets also available to be purchased using the MyMetro app.
Valid passes purchased as part of a season ticket or on the Swift card were also accepted, a spokesperson added.
