tubework

"It is inscrutable," Philippe said quietly, almost to himself, jotting in his book beside his sketch of the tubework.

Introduced in 1949, it had an open tubework tailboom reminiscent of the Bell Model 30, ship number 3, and a three-seat configuration.

The programmes that the repairman had loaded into the construct's analytical engine sent extraordinary instructions coursing throughout the crafted tubework cerebellum.

Taking into account that the line had only light trackwork, heavier locomotives were out of the question without changes to the wheel arrangement, although extra power could be made available with changes to the cylinders or boiler tubework to increase the heating surface and so the tractive effort.
