subway line 11 transfer

hello, i am currently in Anting for business. Last weekend went to Shanghai and took a subway back to Anting. The line is Y shaped and I knew that not all trains are going back to Anting, some go to Jiading. Unfortunately they did not announced in english which direction the train goes and i ended up being in wrong station at the end.
I know one in every 2 trains goes to Anting, or something like that, but is there anything else what would help me to get into right train?

thanks
