In 2008 the Skoda built 37E type electrics were still extremely active, handling the majority of spoil and coal trains around the opencast mine. No.1513 hauled an empty spoil train through Kuangwuju station on 10 October 2008. I didn't get a close look at the builders plates on these locos but they appeared to be in Russian rather than Czech or Chinese (later confirmed to be in Russian Cyrillic script).
