Video: BBC - Tube Delays Redefined What do we think? I personally don't think it makes a difference to anyone but the managers who get performance related pay/bonuses. I've been on peak tube services that take 4 times as long to do one station, yet "Good Service" has been displayed. Other times its been "Severe Delays" and I've had a smooth & fast journey with frequent trains... :roll: So changing the timings won't really make a difference. It's got to be what defines the delay in the first place.
