Not so. The electric part of a standard diesel-electric locomotive is just a transmission, so calling one a hybrid is like claiming an automatic transmission makes a car a hydraulic hybrid.

There apparently are a few experimental hybrid locomotives used as switching engines. And in some places in Europe (I remember seeing one in Finland some years ago), there are hybrid diesel-electric systems that pull power from overhead wires when available, but run on the diesel engine otherwise.
