"Passengers going to Kita-Futo, please change the train at Shimin-Hiroba Station."
The above is an announcement we hear in automated monorail cars operated by the Kobe municipal government.
Is it okay to say, "change the train at..."?
I thought that I had to say, "please change trains at...."
Actually the expression 'change trains' is a general instruction and hence is more appropriate usage
However, in this case 'change the train' is quite acceptable as the passenger/listener is concerned with his train which is 'the train'
or it could have even been 'change your train'
