HORROR, NEARLY KILLED!!!
My first (and last) TPG train: went by bus tour Kharkiv-Sozopol. I additionally booked a place for 5 euros (from Kharkov). As a result, he sat down in Nikolaev (cut off by train). My place was taken, with fights and calls to the tour operator knocked him back. Further: in western Ukraine, where the roads are broken, the driver fell asleep at the wheel and we almost fell into a ditch.
