Sunrise Yume

I want to know about seasonal train Sunrise Yume and its website about Fare,Departure and Destination point.My Nihonjin Friend tell me this seasonal train running overnight from Tokyo to Hiroshima.
Do you think she give me true information or just bluff/Kidding.Your comments are Highly appreciated.

That train is NOT bluff/Kidding,
BUT, already no operate, last train was in 2008(fr 1998), so pretty old info, worthless.

Now no such seasonal night trains operated in that section as until Hiroshima(=after Okayama and Kurashiki).
Regular "Sunrise SETO/IZUMO(2 trains set as 1)" still operating everynight, just not going to Hiroshima.

2 trains(7+7=14 cars total) will be separated/joined at Okayama stn.
