Postal Delivery from rail road cars

Nancy and Dennis looked at the recent mailcar post http://justacarguy.blogspot.com/2013/01/way-back-when-us-post-office-was.html and commented about this very action you see above you,

 the mail was transferred when the train did not stop in a town.

when the train came through it would leave a bag on the first one and pick the bag off the second one. 

 I vividly recall going with my Grandfather to the train station in Canton, NY in the early 50's: he would hang a mail bag on one of the posts, then the train would come through without slowing down, and BLAM - BLAM! The bag he hung would be gone and another bag would be swinging on the other hook!

Way back when the US Post Office was profitable, they had mobile post office railcars processing mail while between towns

 as rare that a mail car is, there is another in this same county... in the Escondido Grape Day Park

Atchison Topeka and the Santa Fe cupola Caboose #1413 built in 1923

I found 2 Pullman passenger cars, in the middle of nowhere. One restored and for rent, the other, probably never will be

 

last of the San Diego class 1 streetcars

I think these are two of the 3 that were quite recently combined to make one residence in El Cajon

McDonalds in railroad cars... might be the only one in the world that isn't in a building, but in freightcars. Barstow Station

It is empty in these photos because I got there about closing time.

From their website, a McDonalds in Barstow (California on route 66, at the intersection of Interstates 40 and 15)  was the biggest in the world in the 1970's, and a guy bought it, plus bought the railroad cars, and put together 17 cars. He made the combined cars connected to use as a multi restaurant establishment, and now it has a Panda Express, McDonalds, Greyhound Bus line, a liquor store and a ice cream store. http://www.barstowstation.net/
