According to the order book, this wood-burning Prairie was ordered for the 3-foot gauge but "Changed to 4' 8 1/2" by E & W L Co.". Connelly shows the engine as a tank locomotive, but the specs show an 8-wheel tender. Also, references documented the E & W said they always ran on 3-ft gauge, 56-lb track. So Locobase supposes that the 1 was convertible to standard gauge, but never actually so transformed.
E & W was based in Eufala, Wash and maintained its lumber road until 1926. The #1 was scrapped in 1929.
Locobase 11492 notes a gauge confusion regarding an earlier E & W Lumber Company engine, in which it is supposed that the 1904 tank was convertible to the 4' 8 1/2" gauge but never actually so modified. So what are we to make of this much larger wood-burning tender engine? It has a big boiler, but a small grate and firebox and logging-road sized drivers.
In any case, the engine faced 36-deg (159-ft radius) curves and 5 1/2% grades. Based in Eufala, Wash, the 2 served the E & W until it was scrapped.
