Could LNER use two Class 91 locomotives powering together?

Could 2 Class 91’s be used on formation to help with acceleration?

I think this has been discussed before and it was told that there would be no difference as there can only ever be one 91 working at once. The other would be effectively dead - so would only add weight.

Firstly I'm not sure if the power supply can cope with that everywhere, secondly you'd need an additional TOE vehicle in each set to couple the other 91 to the coaches with unless you just left the DVTs in the sets.

Bringing this back up I saw a video on YouTube where two 91’s with both pantographs were being prepared for testing on the Midland Mainline on the East Coast Mainline. So two 91’s working together can work on the East Coast. Can this now be applied to passenger service.

NOT MY VIDEO-CREDITS TO OWNER.

The 91's weren't powering - a thread elsewhere on the forum stated they were being used to test the OHLE.

Is this the most powerful train to run on the network? And what was it's purpose?

I've seen various pictures and footage of these workings today: https://www.realtimetrains.co.uk/train/R02736/2020-08-06/detailed https://www.realtimetrains.co.uk/train/R02737/2020-08-06/detailed With 2 HST power cars and 2 class 91s, which were all taking power, that makes 17,100 horsepower...

Reasons they can't be used in pairs in passenger service have been mentioned above!

Thanks, didn’t know they weren’t powering.
