The BAM departs from the Trans-Siberian railway at [[Tayshet]], then crosses the [[Angara River]] at [[Bratsk]] and the [[Lena River]] at [[Ust-Kut]], proceeds past [[Severobaikalsk]] at the northern tip of [[Lake Baikal]], past [[Tynda]] and [[Khani, Sakha Republic|Khani]], crosses the [[Amur River]] at [[Komsomolsk-on-Amur]] and finally reaches the [[Pacific Ocean]] at [[Sovetskaya Gavan]]. There are 21 tunnels along the line, with a total length of {{convert|47|km|mi|abbr=on}}. There are also more than 4,200 bridges, with a total length of over {{convert|400|km|sigfig=2}}.<ref name=yates>{{cite book |url=http://trailblazer-guides.com/books/ |author1=Yates, Athol |author2=Zvegintzov, Nicholas |title=Siberian BAM Guide: Rail, Rivers & Road'' (see excerpt)'' |year=1995 |edition=2, 2001 |publisher=Trailblazer Publications |location=England |isbn=1-873756-18-6}}</ref>

Of the whole route, only the western Tayshet-[[Taksimo]] sector of {{convert|1,469|km|mi|abbr=on}} is electrified. The route is largely single-track, although the reservation is wide enough for double-tracking for its full length, in the case of eventual duplication. The unusual thing about the railway is that it is electrified with a 27.5 kV, 50&nbsp;Hz catenary minimum height at {{convert|6.5|m|ftin}} above top of the rails to suit double-stacking under the overhead wires on the [[Russian gauge]] tracks, which requires rolling stock to be modified for service on the railway.

At Tynda the route is crossed by the [[Amur–Yakutsk Mainline]], which runs north to [[Neryungri]] and [[Tommot]], with an extension to [[Nizhny Bestyakh]] opened in 2019.<ref>{{cite news |url=https://siberiantimes.com/other/others/news/siberias-amazing-new-railway-the-permafrost-express-opens-to-passengers-this-month/ |title=Siberia's amazing new railway - the 'Permafrost Express' - opens to passengers this month |publisher=The Siberian Times |date=22 July 2019 |access-date=25 January 2023}}</ref> The original section of the AYaM connecting the Trans-Siberian at Bamovskaya with the BAM at Tynda is also referred to as the "Little BAM".

During the winter the passenger trains go from [[Moscow]] past [[Tayshet]] and [[Tynda]] to [[Neryungri]] and [[Tommot]] and there are also a daily trains from Tynda to [[Komsomolsk-on-Amur]] and from Komsomolsk-on-Amur to [[Sovetskaya Gavan]] on the [[Pacific Ocean]] via [[Vanino]] (''"Vladivostok-Sovetskaya Gavan"'' train No.351Э). Travel time from Tayshet to Tynda is 48 hours.<ref name="rzd.ru">{{cite web |url=http://rzd.ru/ |title=Новости компании |trans-title=company's news |language=Russian |access-date=2014-02-05 |archive-date=2012-12-25 |archive-url=https://web.archive.org/web/20121225180217/http://rzd.ru/ |url-status=dead }}</ref> Travel time from Tynda to Komsomolsk-on-Amur is 36 hours.<ref name="rzd.ru"/> Travel time from Komsomolsk-on-Amur to Sovetskaya Gavan is 13 hours.<ref name="rzd.ru"/>
