Steampunkvehicles.tumblr is on a mission to post enormous amounts of railroad inspection cars. bravo!

the above gets my vote for most elegant inspection car... those couches look comfortable
 the above is the 1876 balloon car from Larkin st to Woodward's gardens, built by Henry Casebolt

get a look at the front windows, I think there are 6 tilting panels
 1910 or earlier is my guess, one big old tourer, comfortable too I bet.

portable turn table, because as I just recently learned from Steampunkvehicles, the darn cars only cool properly when the air is rushing in through the radiator in the proper direction

  I think the above and below are the same vehicle

 Above a Buick, below a Dodge
