. Railway master mechanic [microform] . y using even moderatelysuperheated steam in the case of stationary en-gines, have led the management of the Prussian Staterailways to make trials with locomotives using moderate-ly superheated steam. The Breslau management fitted two express locomo-tives with the Pielock superheater, shown in figure 1, in ^Abstract of paper by Mr. Strahl, railway engineer,Royal Prussian State Railway, Breslan District, in theBulletin of the International Railway Congress. order to compare them, both as to water and coal con-sumption, with the other locomotives of the same type,but without superheaters. This superheater can be fitted to the ordinary locomo-tive using saturated steam, without altering the boileror the mechanism. It is exactly for this reason that itis specially suitable for comparative trials, and in thisway it has afforded valuable information. The follow-ing table gives particulars of the locomotives and ofthe superheater, as well as the observations made andthe results of the trials:.
