Hi im interested in becoming a installer or tester. Last year i completed an apprenticeship in Pway renewals and after spending a year on the track i gained a massive interest in signalling. im finding it hard now to get an apprenticeship as im 20 and i've searched college sites to see if they do city and guilds level 2 or 3 in railway engineering (that's based on signal installation) but no luck. Although i can study the course at a city and guilds center but i need to be linked with a company so they know get regular practice.(asked loads of companies they said no) 
Any advice

Any advice
