CALS Boiler Info

The state of Maryland requires all model boilers to be inspected and a license issued that is good for one year.  The state will recognize other State inspected boilers but not club inspected.  The Maryland State Inspectors can be reached at 410-767-2990 for questions or to setup an appointment for the inspection. 

For those wishing to visit and run on our track we will be happy to assist.

Calculations for Traction Effort, Curves, and Boiler

My thanks to Rich Dean for pointing out an error on the boiler Staybolt calculation.  I apologize for any problems this caused.

Here are some sample of the spreadsheet program available in Excel .   There are three parts, one will calculate the max load that an engine can pull up different grades.  Another will find the Versine of a curve (draw a line between two points and it will show the distance from the center of the line to the edge of the curve.   Useful for deciding how much flex is needed in the engine wheels.)  The last part has the Maryland Boiler Code calculations.  All of these are for guidance only and should not be the sole basis for any designs.  Download the program here.

From L to R are John O’Dea and his Mogul, “DOC” Kinzer and his Mogul, Ed Diehl’s Pacific, Ed himself is missing, Lou Koehler and his blue Atlantic, Leo Chism with his Pacific, Larry Kirchner and his Mikado, The arm belongs to Skip Rollins while the Pacific belongs to Lou Kohler, yes we do have two different Lou’s.

(The above photo is getting a bit old, both Lou’s, Leo Chism, and Ed Diehl have passed away.)

Any members that would like their engine information posted sent me a picture and the information. seyfritp@verizon.net
