there is a direct night train leaving at 19:09 and arriving at 9:58 in the morning. it is $471 for 2 in the first class Grande cabin (I guess that is the Excelsior), and $342 for 2 in first class double (T2). the difference is that Excelsior has a toilet, shower and breakfast, where T2 has only a wash basin. you can see the detail of night train here:
