When trains are due: Abbr (4)

Ross

I believe the answer is:

etas

(Other definitions for etas that I've seen before include "Makarios' letters" , "who once did menial tasks in Japan?" , "Greek characters" , "Characters in Greece" , "lowly workers" .)

I've seen this clue in the Newsday and the Newsday.com.
