It will be one of 6 which remain in active service to be withdrawn, the others being 4944, 5229, 5230, 5231 and 5232, the other Euro 4's have either been withdrawn already or are driver trainers.

And 5201 was not the first of the penultimate batch to be withdrawn either, 5203 was way back in January of this year.

The first of the penultimate batch to be purchased Andrew says - not withdraw.
