Hi Richard and welcome to the forum!
The simple answer is yes, any DCC fitted loco should run on any DCC controlled layout.
However the Hornby Select is known to have a few problems and although it's OK for starting out in DCC, you may be better saving the money and instead of buying the Class 57 right now, buy a new controller instead. There is a lot of information and reviews in the DCC section of the forums. I personally would recommend the NCE Powercab but there are many options out there.
Hope that helps,
Rob
