Regrettably, I have no photo for those Siberian track inspectors/workers. (I read of them and saw them in a documentary only.)

But, here is a link for the famed Transsib, and another for its more northerly sister, the BAM - both with lots of photos.

Also: while I consider this the hardest job, the 'job' of forced or slave labourers was of course even harder - and the Transsib was built by such men, while the BAM was begun this way under Stalin.

How the BAM was finished is also interesting: in a last giant propaganda coup of the communist regime, young people were called upon to do the construction on their own, with the promise that they can settle in the new settlements along the line. But the economic miralce didn't happen, those who settled have to struggle to this day, and traffic along the maintenance-intensive and deficitary line is catching up only now. A few photos with workcrews during construction can be seen here, below one that shows how newly laid track looked on the permafrost:
