Physically, K 900 retains its original boiler, tender and plate frame, the latter showing evidence of extensive welding repairs due to the weak nature of the original construction. It appears much as it was when withdrawn, with the recessed K-style headlight, but with a KA style funnel and a cross-compound pump with twin air reservoirs mounted under the front compressor shields. There are plans to move the locomotive to the Western Springs Railway for storage, but possibly also to restore the locomotive to working order.
