I was under the impression that when Colas bought and reactivated each of their Class 56s, they refurbished them before they re-entered service - hence Class 56/3. However, I've noticed they have a few which still carry their original BR-era numbers.
What's the difference with the 56/3s compared to the originals?
Thanks!
