The Modern Steam Locomotives

The Modern Steam Locomotive 

By Donnell E. Allen Jr. 

I plan on completing a few research essays addressing different components of the steam locomotive that made them "modern" between 1920 and the end of steam operations in 1960.

Topics include:

• One-Piece Cast Steel Locomotive Beds
• Locomotive Boilers and Fireboxes 
• Superheaters
• Combustion chambers
• Brick arches
• Feedwater Heaters
• "Super-Power Locomotives
• The Lima Locomotive Works
• The integration of the 4-wheel-trailing truck 
• Locomotive Boosters 
• Modern Locomotive Appliances
• Front-end Throttles 
• Locomotive Valve Pilots 
• Boiler back pressure gauges and other instrumentation     
• Safety Appliances
• Low Water Alarms
• Signaling and communication equipment   

As usual, being a fan of the Norfolk and Western Railway, many of my examples will reference that road.

I'm always open to suggestions and feedback. Feel free to contact me with your ideas.
