Great observation! It might seem strange for an electric locomotive to make steam locomotive sounds, but it's possible the sounds you're hearing are actually from a sound system installed on the locomotive. This is done for a variety of reasons, one of which is to maintain some of the traditional aesthetic and sounds associated with train travel, or to make the locomotive's presence more noticeable for safety reasons.

why does an electric locomotive make steam loco sounds?

@hellamax789 We have these things called "Horns" which serve the exact same purpose.
