I found this on the government careers website
Tram drivers take passengers to and from destinations, following a set timetable.
nationalcareers.service.gov.uk
It mentions a Level 2 Diploma in Rail Services (Tram & Light Rail Vehicle Driving), and it also suggests that you can start as a passenger assistant or conductor and move into driving work after taking company training.
I see that your location is Manchester.
Have a look at
https://www.metrolinkjobs.co.uk/faqs/ which lists their requirements for becoming a tram driver
You will need to meet the following criteria:
- Full UK driving licence
- No more than 3 points on your licence
- Driving for at least 4 years
- No drug or alcohol convictions
The company carries out background checks on individuals applying for the driver role with the DVLA before proceeding to the next stage of the recruitment process.
