This paper model is a KPEV T-3/Br 89 Locomotive, created by Bastelbogen Online. The scale of this paper Locomotive is in 1:45. In 1881, the Prussian State Railways ordered their first T-3 locomotives, unaware that this design was destined to become a world famous classic. To many railfans, the sight of T-3's unmistakable silhouette conjures up romantic visions of lonely branch-line operations with the tiny locomotives hauling a string of four-wheeled coaches into yesteryear. While it may be difficult to pinpoint exactly what endears the T-3 to railfans, there is no doubt that the locomotives' reliability and operating characteristics endeared it to both its engineers and owners. A total of 1550 T-3's were built between 1881 and 1906 with 1345 of these going to the Prussian State Railways. The remainders were used on privately-owned lines both in Europe and elsewhere.
The T-3's reputation was based on her simple yet ingenious design. The boiler was exceptionally efficient and generated fairly dry steam in spite of not having a superheater. The firebox grate area, originally 13sq ft was later increased to 14.5sq ft; the firebox squeezed in nicely between the last set of drivers. The 43 inch diameter drivers were supported at three points making the locomotive quite stable. The ancient Allan-Trick valve gear was almost humorous in its operation but did its job well. However, time eventually caught up with the T-3; when branch line speed limits were raised from 30 mph to 40 mph; her speed capability of only 28 mph relegated her to yard duties for the remainder of her career.
