Interesting load on a SAL flat
Brian Termunde
On one of my Milwaukee Road lists, the attached photo was shared. He was interested in the load, any ideas?
Thanks! Take care Brian R. Termunde Midvale, UT

They are watertube boilers. Similar to marine boilers. They are the opposite of firetube boilers which were commonly used on steam locomotives where the combustion gasses go through the tubes and water surrounds the tube. In these, the water/steam is inside the tubes, while the fire is outside them. In operation, these are much safer than firetube boilers. And, before you ask, several roads did experiment with watertube (or a hybrid design) boilers... unsucessfully. The B&O was the major road that used a variety of them, but other roads did experiment (including the PRR). The big advantage of firetube boilers in locomotives was the large reservior of water in the boiler that was at the boiling point for the pressure inside the boiler would respond instantaniously to a lowering of pressure inside the boiler due to increased steam demand. Lowering the pressure caused more water to flash to steam without the crew's action. This was valuable in locomotive use, but not so much so in other, steady-state applications.

Here's an earlier version of a water tube boiler on a flat car, from Saginaw, Michigan in 1895.
The Flint & Pere Marquette was one of the predecessors to the Pere Marquette, which owned the second flat car in the photo at the top of this thread. - Fritz Milhaupt

All- I wonder how far that excess height load got before taking out a wagon bridge or wires crossing the track?? Charlie Vlk

There was an annual publication titled "Official Railway Clearances Guide" from the same folks that printed the ORG and the ORER. its purpose was to show the vertical and horizontal clearances of each stretch of line in North America. Every significant agency had a copy and I'm sure that every shipper who originated high & wide loads also had one. Scott Chatfield
