Please tell me any info about a trip using the Baikal Amur Rail From Taischet to Sovetskaia Govan. Cheep trains.
Well, you don't have a big choice here... There is no direct train from Taishet to Sov,Gavan via BAM, but only direct carriage via Transsib (attached to #2 "Rossiya" train). In order to go by BAM you will need couple changes: in Tynda and Komsomolsk-na-Amyre.
Taishet-Tynda: train #76 (Moscow-Tynda) every second day (+some other on days of the week), "kupe" upper berth from 2257 RUB (lower berth twice as much). From Tynda to Komsomolsk there is everyday train #964, upper "kupe" 1367 RUB (lower - twice as much). Komsomolsk to Sov.Gavan: everyday train #943 Khabarovsk-Sov.Gavan, upper 'kupe' 659 RUB (lower - twice as much). All the fares for mid October, so you be ready for slightly different fares in case you travel during other season (RZD has this special seasonal coefficient, so fare depends on date you travel).
p.s. in case you prefer cheaper 'platskartnyi' carriage - let us know, so we will give you 'platskartnyi' fares.
