Possibly to give the locomotive walls more rigidity?

Se intreaba pentru ce sunt peretii ondulati.

Pentru CFR au fost fabricate 3 locomotive cu acest tip de cutie.
EA 657 , EA 705 si EA 721.
A fost o initiativa a anului 1984 , care din mult spirit de economie , caracteristic acelor ani nu s-a pus in aplicare la urmatoarele locomotive fabricate la IEPC.

The ideea was to save material, by ading the corrugated feature to the metal sheet this sheet can be made thinner but mantain the same rigidity. The ideea was abandoned for electric locomotives but was implemented with much less corrugating for diesel-electric locomotives.
