Discover a fairly routine racket of con-men riding the trains trying to set up easy pickings on arrival - or worse. They're usually well dressed, middle aged men apparently returning home just like the traveller. They are overly friendly & enthusiastic, quickly extracting details of your journey & where you're staying. Be vague & not too friendly. On our 4 hour journey we had 3 men joining our carriage & when getting little response they upped & left, targeting foreigners in subsequent carriages - nobody simply loves foreigners that much, unless they are after something.
