One of the Best Kdrama in 2020..Every episode is having many twists and mysteries..Versatile actor Yoonshiyoon's Triple Role and Ost is Biggest plus point to Drama. Cinematography is too good, one Scene in Episode 11 where Seodowan A will be walking in Railway track in World A and Han B also walking on same track in World B which is marvelous . Every Cast member is having equal role in this Successful Drama. Director and Writer showed us Multiverse without creating any confusing..Everything is interconnected. Hope We need #Train2 season 2 to watch much more Multiverse in future with same case. OCN Never Disappoints..??.
