Severn Valley visit 30 years ago.

Complication

Simplicity 

I can remember I got a lot of micky taking from John and Robin because I took a pic of a little diesel shunting loco cab interior.

I wanted to emphasize the easyness of driving a shunter like that and the number of controls on a steam loco.

Must have been at least 30 years ago - I wonder what the next stuff to turn up will be.
