Class 66 light loco on WCML fast lines?

[Peregrine 4903]

Today I was travelling on the 16:53 Avanti West Coast service from Milton Keynes Central to London Euston and when passing roughly North Wembley I saw a light loco class 6 pass us on the fast lines. What was also odd was that the loco was running between the 17:03 to Birmingham New Street and the 17:07 to Liverpool Lime Street. There is definetely no service booked to run at this time of a light loco class 66.

Does anyone know why this light loco class 66 was running?

I checked on RTT and couldn't find it.

 

[Class 170101]

Probably something has failed and the Class 66 has been commandeered to remove it and thefastest way to do it is on the fast lines with all the other non-stop traffic.

It might've been 66070 going to rescue failed 90026. The 66 ran 1Z99 from Wembley Yard to just north of Cheddington where the 90 had failed.

It was a DB red liveried 66 so that sounds about right. As it was running on the fast lines I presume it must be have been a rescue loco. Thankyou so much for being able to identify the loco and what it was doing.
