Adams Express, American Express, Southern Express and a few others were merged into the Railway Express Company (REA) in 1917. The Feds needed to control the railways for the WW1 emergency. It was accomplished by the United States Railway Administration (USRA) to assure that that the Rail Systems operated efficiently during wartime. Railway Express was with us until 1975 when it went out of business. The Interstate Highway System became their downfall when UPS et al went into the over the road delivery business.

The look on his face tells me that the bike frame just might be causing him a wee bit of discomfort.

Perhaps he is telling Hines to "Hurry up and take the picture.....this is killing me!"

Adams Express continues in business today. Like other express companies of past centuries, such as American Express and Wells Fargo, their principle business became financial services.

Except for the center bike with the auto horn and spring seat, these bikes look like they had earlier been board track racers.
Bare bones frame with serrated metal pedals, smooth tires, sans chain guard and rigid racing seats. Just reset the handlebars downward to racing position. Tuck in, and ride like the wind.

Although the coaster brake was invented a little more than ten years before this picture was taken, they weren't ubiquitous yet, but the second bike from the right does appear to have some kind of band on the left rear stay, possibly to secure a torque arm...
