The Challenge (1998)

S7E25 Trusty Rusty

While pulling a train over an aging wooden bridge, Rusty spots some loose joints. Concerned, he informs the Fat Controller, who promptly shuts down the bridge for repairs. Rusty shares this news with the other engines, but Duncan dismisses his warning, calling him a silly diesel, and leaves without refueling. Later, in need of coal, Duncan heads across the bridge, but he runs out of steam midway. Stranded and helpless, he watches in horror as the bridge begins to give way beneath him...
