Arriva North West - Winsford Depot

[R311 WVR]

RE: Arriva North West - Winsford Depot
4216 had a problem (A Loud, Annoying one) that has now been rectified, it was a very loud "Beep" when slowing down coming from the rear, and also when setting off, I don't know what it was but it was awful!

I had 4216 yesterday and have to say it was still slower than 4215, But still better than previous times i've been on it!

I noticed 4215 on the 20:30 37 Crewe-Winsford (Or Middlewich, as the destination displays!), What does this come off as I didn't see it on the 37 previous on the day?
