At least they hopefully weren't screaming "My Lords!" (Painful memories of the last days of the 'Westerns' in 1975-77).
I'm pretty sure I heard that at least once...
Meanwhile, the second to last train of the day into Kidderminster yesterday (40106) was an hour late departing Hampton Loade, arrived Kidderminster only half an hour late. I was sat in the third coach (deliberate decision) which was peaceful, other than the group of teenagers in the vestibule and the sound of 40106. The front two coaches, however, were incredibly noisy and rowdy. At Bewdley, a rumour spread amongst the younger passengers that the run through the tunnel would be "spirited". And indeed it was, in more than one way!
We slowed to a crawl just before the tunnel, then the driver gave it full power until we were out the other side. It was very loud! However, the EE noise was almost drowned out by the absolute raucousness from the front two coaches, which reverberated very clearly in the tunnel.
A very good day out, on the whole.
