kuid2:211427:15153:2 (TRS 2006) or kuid:203201:3 (TRS2004/2006)
Both are DEV 152 Tankcars the first has some animation of loading pipes ('though I've never seen them actually operate in the game) and end of train marker disc - the second one has no animation and no marker.
The DEV 152 was first made available for 1000mm gauge, but I am given to understand that 760mm/30in is also prototypical.
There is also a 760mm/30in silo wagon kuid2:121794:99801:1 and/or kuid:121794:99802. It is configured to load Talcum but, if you are not too fussy about prototypical rolling stock, it can reskinned and reconfigured to carry liquids - animated loading pipes and end of train marker on both models. I'm not sure but these might be TRS2006 only.
