Note: the above is from newspaper articles, Baldwin specifications sheets and Best, Ships and Narrow Gauge Rails. There is a roster included in Roberston’s Encyclopedia of Western Railroad History, Vol III (under Seattle and Walla Walla but includes information about the SC&T Co locomotives) Robertson’s account confuses the SC&T and S&WW, has significant errors and should not be relied on as a reference.

Rolling stock.

The coal cars were 4 wheel, wooden body, 8’ long, 4’ wide, 2 1/2 ‘ tall with a capacity of 2 tons.

In January 1875, the sternwheel, steamer Chehalis was pulling a barge containing 18 wooden coal cars across Lake Washington. As the Chehalis was rounding the northwest point of Mercer Island, a gale blowing from the south struck the steamer and barge. The wind tipped the barge and sent the 18 coal cars plunging to the bottom of the lake. The wooden coal cars remain where they sank, well preserved in the cold (45 degree) water, most of them upright and still carrying their cargo of coal. ¹
