Pros: Left on time and arrived nearly on time. Slippers, a hot meal with wine, and earplugs were provided. Very comfortable leather upholstered seats, with large picture windows. Smooth ride (train built by Siemens of Germany). Arrives near downtown St. Petersburg, a short taxi ride to most hotels.
Cons: Unless you board early, luggage storage space is limited. If you book outside Russia, be sure to have your ticket number when printing ticket from train station lobby machine, otherwise you may have to see the station master (which requires an interpreter). Wi-Fi is advertised, but did not work at all on my journey. The journey is not picturesque (take reading materials or sleep).
Summary: Better than flying
