The cops chase them until they come to the edge of a steep street and then.............
Compounds and Superheaters
An inventory of main-line steam locomotives in the United States as of 1904 shows that, of 233 Pacifics in service, 85 were four cylinder compounds. The reasons for the introduction of compounds, to oversimplify, was that they were more economical on fuel, and, a factor particularly important to those railroads out West where water supplies were limited, and the water was of poor quality, compounds also used less water. Thus, the Atchison, Topeka and Santa Fe, which had compounds in many wheel arrangements, built 196 four cylinder "balanced" compound Pacifics between 1905 and 1914, although it should be pointed out that at the same time the road was also buying two cylinder simples of the same wheel arrangement. 4
The reason for the decline of the compound rigid frame locomotive in the United States was the general introduction of the Schmidt type superheater, which offered both fuel economy and better performance without the maintenance and construction costs of the compounds, although, in all truth, superheaters presented problems as well. So, most of the Santa Fe compound Pacifics were converted to two cylinder superheated locomotives, and enjoyed a long and successful service life. (During the mid 1920s, largely promoted by ALCO, there was considerable interest in three cylinder simple locomotives. There were a few three cylinder Pacifics built for Mexican service, but there was no series production of such Pacifics for any US or Canadian line.)
