Santa Fe No. 4076

The Santa Fe (ATSF) No. 4076 was a 4000-class 2-8-2 "Mikado" type steam locomotive built by the Baldwin Locomotive Works in 1924 for the Atchison, Topeka & Santa Fe Railway and one out of the 101 Santa Fe (ATSF) 4000 Class 2-8-2’s built between 1921 and 1926 by Baldwin Locomotive Works.
On July the 13th, 1951, Mikado no. 4076 - along with fellow Mikado 3167 - were among ten Santa Fe steamers, all awaiting scrap at ATSF's Topeka railroad shops. The locomotives were moved over to the adjacent railroad bridge over the Kaw (Kansas) River, to keep the bridge from washing out during the intense flooding of the river that year.
Two of the five spans of the bridge ended up being weakened and gave way, taking the two aforementioned locomotives with them. When the floods subsided, they were left in situ as steam was already being phased out in numbers at the time. Although it was presumed that whatever remains of it still exists, nothing left of 4076 has been found to this day.
Note: It has been lost until recently when a local railroad history buff took notice of the story of the 4076 and did some research that uncovered some interesting details that could lead to the rediscovery of the engine. From aerial photographs of the fallen bridge span which collapsed during the flood, one might see a noticeable block sticking out of the water on the northern part of said span. By doing some research onto the topic, one might find a post on Facebook which matches the aerial shots to a T and says that it's the remains of a tender which belonged to one of the engines. 
Another photograph from the day before and days after the bridge span fell, one could notice a little number on the engine which was located on that span which collapsed into the river being eerily similar to the number 4076.
It might be possible that the engine is on its side, encased within the bridge with its cab crushed on impact as the bridge fell.
