You have probably damaged the HST motor by running a DC loco on a DCC controller........HB

I agree. Never put  a DC loco on a DCC track, unless you enjoy changing motors.

Let me just fill in a bit of detail.

.

OL on the Select means OverLoad. This is the Select telling you that it is seeing a 'short circuit' on the track.

.

As others have said, in all likelihood you have burnt out the DC motor in your loco. The windings have over-heated and burnt through their insulation covering. This causes the motor to present a 'short circuit' to the controller. Your loco now needs a new motor or the old motor to be re-wound. Just because the Hornby Select instructions state that you can control a single DC Analogue loco using the Select controller. The 'small print' in the Hornby manual also says, that the practice is not recommended. Always install a DCC decoder to an Analogue loco before running it on a DCC track ... the decoders are a lot cheaper than replacing the motor.

.

If you leave a DC loco stationary on a DCC powered track, burning out the motor is inevitable.

.

Many manufacturers are removing this Analogue feature from their controllers because of the motor damage it causes,
