Aster 1975 年製台灣阿里登山車, 現已不多見, 以蒸氣為動力, 只是與現有的26號的煙囪, Tender 等差很多, 這款是 Lima最初的的原型車嗎? 台灣的阿里山火車再後來有做大幅度修改.
阿里山蒸汽火車簡介:
黑色精靈阿里山蒸汽火車，直立式汽缸及傘形齒輪傳動機構，不知風靡多少人群。這是由美國 LIMA公司製造的，其特殊的設計是為了克服行駛載運木材的火車在山地鐵路上行駛時所遇到的種種問題如：打滑、停車時會滑動等而設計的。
28噸Shay蒸汽機關車:行駛於阿里山森林鐵路全線，是蒸機時代的主力。

Aster Shay Geared Class B - 2 Truck Specifications
Made in 1975 by Aster
The Geared Logging Locomotive was born of a growing and all-the year round need for timber in the 1870's. Ephraim Shay invented the geared locomotive with a vertical engine, since ordinary steam locomotives were incapable of running on rough and crooked tracks in mountainous areas. The Shay was the first geared logging engine and became the most popular form of haulage during the 1920. Due to the use of powered trucks, moving at a very slow speed, the Shay could easily negotiate rough track, sharp curves, and steep grades. Shay Geared Locomotives continued in use well into the age of Diesels. The prototype of this shay modeled by Aster replicates a locomotive Lima working on the Alisan Railroad in Taiwan.
