FIG. 10. EXPRESS LOCOMOTIVE, PRUSSIAN STATE RAILWAYS. BERLIN ENGINEERING COMPANY is operated from the return crank bya rod extending backward instead offorward, as usual. The firebox is steel, stayed on theJacobs-Shupert system, and oil fuelis used. The smokebox contains aSanta Fe reheater. The steam pipefrom the dome is carried outside theboiler and divides to each high-press-ure cylinder. The exhaust fromthese cylinders passes to the reheaterand thence to the low-pressure cylin-ders. The 4-6-0 wheel type is still in verygeneral use, and in many quartersconstitutes the principal express classfor heavy traffic. On the GreatWestern Railway of England are, forexample, engines having four high-pressure cylinders, a Swindon super-heater, a taper or conical boiler, ahuge Belpaire firebox, and the highsteam pressure of 225 pounds persquare inch, and have to conductwhat are probably the most remark-able train services in the world.

FIG. 11. NON-COMPOUND PASSENGER ENGINE, OF MODERN PRACTICE IN RUSSIA. ENGINEERING COMPANY KOLOMNA REMARKABLE LOCOMOTIVES OF 1910 in loads range up to 400 tons in thesummer, but they have to cover 117J/2or nSy2 miles in 120 minutes, 173^miles in 180 minutes, and 225^ milesin 247 minutes, the last mentioned in-cluding 30 miles of terrific gradients,while other sections are by no meanseasy, though possibly not particularlysevere. For several years a remarkableclass of 4-6-0 express locomotivesfitted with Schmidt superheaters havebeen in service on the Prussian StateRailways; but in order to complywith still more exacting requirementsthe design has been developed by theBerliner Maschinenbau A-G, withfour high-pressure cylinders, and oneof these interesting locomotives isshown in Fig. 10. Originally, two ofthese engines were constructed, onebeing exhibited at the Brussels Ex-hibition, while the other was severelytested in regular service. The re-sults given have been so satisfactorythat we
