This museum is perfect if you want to know a little bit more about how the Metro of Madrid has worked for years. Here you can find 3 diesel engines and other pieces of machinery as transformers or alternators, useful years ago for the correct Metro operation.
Although it smells a little bit greasy, this visit is quite special, because you can learn more about the main public mean of transport, and it's very related with Madrilenian history. This center was useful also to provide energy to a part of the city during the Spanish Civil War. It was closed in the 70's and re-opened as a museum in 2008.
