Hi Woody & welcome to the forum.
Like most people on here I was keen on trains when I was a teenager. I went onto other things and thought I'd got them 'out of my system'.
However the 'imposition' of a career change in my 30s led me to become a driver. I've now done 17 years on the footplate and absolutely love it.
If you want to see diesel locos, Freightliner is based at Eastleigh. There's lots of container trains going to the docks.
Here's a link...
