If you mean Manchurian as in Outer Manchurian (aka southern part of Russian Far East centered around the Vladivostok), then it is if course necessary, but its’ acquisition is pre PoD (the Convention of Peking was in 1860).The real concern would be China and the inevitable Mandchurian part if the railroad. But again, misusing a quote that has not been huttered yet... Whatever happens, the *insert European power* have got the [Gatling/Maxim/Nordenfelt] gun and they have not.
If you mean Manchurian as in Manchurian Proper there is nothing inevitable in routing the railroad through there. Yes, the route through Manchuria was cheaper (mostly because of plainer relief) but not by that much. Even from the point of length the railroad built to Chinese border and through Chinese territory was only marginally shorter than the railroad built north of Amur River (1894 km v. s. 2051 km). This is of course because the railroad from Vladivostok to Khabarovsk was built in early 1890s anyway (644 km from juncture to Chinese Eastern Railway), but connecting Amur River and Vladivostok was of paramount strategic importance.
Moreover, the decision on building Chinese Eastern Railway was made in the second half of 1890s, when much of the Trans-Siberian Railway was already built. The initial plans were to built the railway north of Amur and these plans were started to implement immediately after Russo-Japanese War.
Overall IOTL the decision to build railroad through neighboring country was an extremely costly blunder that both wasted Russian Empire resources and lead to a rapid development of a massively important region of rivaling regional power. Of course, the plan was to grab Manchuria for Russia and if this was successful then it all would be worth it (so perhaps it should be called a gamble rather than a blunder, but it was a rather desperate gamble).
ITTL even the slight change of circumstance can lead to different outcomes.
If Chinese government is a bit more stable ITTL than Russia can implement its initial plan of Amur railway.
Conversely if Russia reaches Manchuria by railroad a decade, or better two decades earlier than IOTL, the plan to grab Manchuria can be much more successful (the Chinese settlement of Northern Manchuria really took off in 1890s, so if it is Russian territory by then, it potentially can be integrated into Russia in the same way Far East was IOTL; Japan also probably cannot challenge Russia in the region until early 1900s, so Russia can be way more entrenched by the time Japan can be ready to act).
All the technology to build Trans-Siberian railroad is there from 1860s at least. The only thing that really prevented Russia from doing so is the lack of funds. So, if Russia ITTL has wealthy outside investors or if it chooses to prioritize railroad building over e. g. Russian-Turkish war of 1877-1878 (that costed an insane amount of money, more than full cost of Trans-Siberian railroad, helped to liberate Balkans, but lead to very meager gains on part of Russia not to mention that it caused inflation and reduced Russian ability to loan money for decades), it can definitely build the railroad substantially earlier than IOTL.Ah this one gets it!
Is it possible to construct a Trans-Siberian Railroad in the late 19th century? Someone means to find out! But I am getting a little ahead of myself...
Moreover, you should take in mind that even partial completion of railroad would lead to massive changes in Siberia (and also would massively bootstrap Russian economy).
Connecting Russian railway network to Ural Mountains would massively boost Russian heavy industry (some 1100 km in addition to a privately owned "island" railroad from Perm to Tyumen through Ekaterinburg built IOTL by early 1880s; but the local capitalists wanted to build it since early 1860s, so if they get permission from authorities quicker and especially if there is a perspective of this railroad connecting to main Russian railroad net, it can certainly happen in early 1870s).
Going from Tyumen to Omsk, Ob River and the capital of Western Siberia Tomsk (another 1450 km) can bring extremely cheap grain to Ural Mountains and to Russia proper where it can be traded abroad and industrial goods to West Siberia from Ural. Moreover, it would lead to extremely rapid settlement of steppes in southern West Siberia and OTL Northern Kazakhstan (in the first 15 years after the completion of Trans-Siberian railroad the population of Western Siberia and OTL Northern Kazakhstan doubled going from 4 million people to more than 7.5 million; this was the region where the majority settlers in 1895-1915 went). Tomsk is also close to Kuzbass region extremely rich with coal and iron as well as other natural resources that are known since XVIII century but that cannot really be put to proper use without railroad bringing workers and grain to the region and transporting coal, steel and industrial goods to European Russia and international markets.
Additionally, the availability empty and extremely fertile land can potentially soften the situation with freed peasants left without land.
From Tomsk it is 650 km to Krasnoyarsk, a region extremely rich with gold, fur and other natural resources, but where the price of grain is 3 times the price of grain in Tomsk (in other parts of Central and Eastern Siberia it is several times higher).
From Krasnoyarsk it is 1100 km to Irkutsk on lake Baikal, from where it is 250 km to Kyahta on Chinese border that was a center of extremely profitable tea trade (by mid XIX century yearly imports of tea were over 10 thousand tons; through Kyahta around 10% of Russian foreign trade was conducted; more than 10 thousand people were employed in transporting the tea over Siberia and just their yearly wages were around two million rubles).
I can go on, but to sum up Russia definitely could build at least the part of railroad to the west of Lake Baikal in 1870s-1880s.
It would have the length of some 4300 kilometers (in comparison Central Pacific Railroad built in 1860s is 3000 km) in addition to the Ural Railway privately built IOTL (or alternatively it follow the historical southern route without connecting to the Ural Railway, requiring some 4400 km railways built). Moreover, even partial completion (say to Tomsk, which requires 2550 km built) would bring Russia massive economic and strategic benefits.
Now, completing the railway all the way to Vladivostok is another 3100 km if going through Manchuria (and without building any additional railways diverging from main track such as railway to Khabarovsk, Sretensk and Port-Arthur built IOTL before the Russian-Japanese War) or 4100 if going north of Amur.
But if Russia builds the section of railroad to Baikal by late 1870s-early 1880s in the next decade it probably can complete the railroad to Vladivostok.
