moving on from FGW^▸ (First Great Western) stupidity, just to satisfy my curiosity, were both locos running both ways, or was the rear switched off when not in use?

I strolled down to Weymouth station to see the train, but was 15 mins late, and it had already heaed to the sidings.
However I was just in time to see the 5 car 158 formation pull in, stupid thing is it was abolutely packed full of poeple complaining "at least 5 coaches is better than normal"!!!!!

Having read the previous comments about only 50-60 on the 67's obviously none of FGW^▸ (First Great Western)'s customers had any idea that just 10 mins earlier a 6 coach train with tables for everyone had been running just ahead of the sprinter! Absolutely stupid!
