Relief plaque with the coat of arms of Pius IX
The relief, which was made using the electroplating technique, is decorated with the coat of arms of Pius IX held up by angels with the papal keys. The plaque was designed to be attached to the front of the locomotive of the pope’s train and has flag holders on the back. Various vintage photographs show that it was also used with the train now on display in the Centrale Montemartini.

The environment that today is dedicated to the exposition of Pope Pius IX’s train wagons was originally a sector of the Boiler Room n. 2 of the Montemartini thermoelectric plant.
