I'd be surprised if that was too taxing a load for a 47. I wonder if the really slow pull away meant that the AWS/TPWS tripped as the signal seemed to go back on before the loco had fully cleared it.
I wouldn't be surprised if it was the loco at fault, it had a similar episode earlier in the week whilst bringing in the stock for 1M11 - departed Polmadie 5E and couldn't get enough power to get up Eglinton St based on a post elsewhere (someone else may correct this if false), arrived into GLC 111L.
