It’s replaced 7580 which has come back to Redcar as it’s due test - presumably it’ll be up next week.
Unsure how many spares Redcar carry but they’ve obviously got one away up north (as does everyone else) from their limited fleet, there won’t be endless buses sat in the depot (which there used to be!). Majority of the scrappers have been moved out too so the yard will look empty during the day.
