I've grown up and lived in Southern California all my life. The scenery on this layout is perfect. Wow! Many of the areas still look very similar today, but some (sadly) have changed considerably. Thank you for sharing this.
I would have liked to have seen more of the station featured, which if I'm not mistaken is the one in San Bernardino. The station still stands, the shops moved to Barstow.. San Bernardino was my hometown and it captured the station and shops very well. I recall a very tall smoke stack next to the roundhouse/shops ( not depicted?) and the Mt. Vernon Ave. overpass ( which is shown).
As a kid I remember hearing the Santa Fe shop whistle blasting away telling the whole town to start the day. It could be heard all over the valley.. You could set your watch to it.
My father in law and brother in law were life long Santa Fe employees. It was a great time growing up in Southern California.
