I think this really only applies to preservation locos though I could be wrong. Most of the fellas I've spoken to give off about how dirty and smelly the railways were (locos included) during the steam era and say that people have just forgotten that through the years with all the nostalgia involved.
Sorry, I veer OT.
Towards the end of steam, things did get grimy & uncared for by the powers that be, but for most of the time prior to that, depots & crew used to take great pride in their allotted loco & tried to keep it as clean & well oiled as they could.
