But then given the reliability of them it's probably best that passengers are given half a chance of getting to their destinations (Whitby/Scarborough) using the likes of 1743 and 4080

Exactly that reason, reliability. I'm sure 7513 has just returned from having a new engine fitted so it may be they're running it in on less demanding territory before sending it back to Whitby.
