   PHOTOGRAPHS OF B&M STEAM LOCOMOTIVES
 
     This site contains photographs from my collection which illustrate all the letter classes of B&M steam locomotives.  In 1911 the B&M adopted a class system which used a letter to identify the wheel arrangement followed by a number which indicated a specific group within the letter designation followed by a lower case letter to further specify a particular group.  The use of the class system changed over time so that it is difficult to generalize about the meaning of a specific designation except that it identified the wheel arrangement and therefore the general use of the locomotive while the number gave an indication of the relative age or size of the engine.  MINUTEMAN STEAM by Harry A. Frye is an excellent source of specific details.
     The photographs in this collection are arranged by letter class and the site map shows the page where the letter class is found.  Letter groups are as follows:  
   
A   -  4-4-0     B   -   2-6-0          C   -  4-6-0       D  - Forney (4 drivers)   E  - Forney (6 drivers)    
F   -  0-4-0     G   -   0-6-0          H   - 0-8-0        J  -    4-4-2                 K  -  2-8-0                
L   -  4-8-0     M   - Articulated     N   - 2-8-2       P   -   4-6-2                 R -   4-8-2    
                          S    -   2-10-2                                    T   -   2-8-4
