Diesel locomotive class 754 of the Czech State Railways.
The so-called diving goggles or spectacle snake was developed and built at CKD in Prague. The T 478.4, which was further developed from the predecessor type T 478.3, received a more powerful engine and an electric train heating system. In 1988, the 86 machines were given the new series designation 754. From 2009, the locomotives used in passenger service were painted in the blue/grey "Najbrt" design.
