Why..., John thanks for the kind comment on my young age. I guess I shouldn't tell my age and say that I've traveled many a mile on passenger trains pulled by those coal fired, black smoke belching locomotives. Or that The B&O is the Baltimore & Ohio Railroad Company.:-)
Perfect POV, perfect crop, perfect exposure, great technical detail, don't know what anyone could do better here. The old steelwork in Voelklingen would be a paradise for you !
Thanks for the comments Jimmy, hope you are doing well. My Dad taught me to look at things and see details, to look at how things are made. He was an engineer. A saddle tank engine is a small "switcher" with the water tank over the boiler. The B & O used to have them, but you are much too young to remember!
