Trans Siberian has Grey at 5, Brown at 4, Natural at 3, White at 2. Total should be 5*1 + 4*2 + 3*4 + 2*7 = 39
St Pete has Grey at 8, Brown at 2, 2x the row is in effect = (8*1 + 2*2) * 2 = 24

Total should be 63, total showing on name is 57

I made the same mistake which brought me to your post and others (where it became clear to me I was calculating my score wrongly).

You should only count the number of tracks _until_ the next colour track. Not all the way back to the beginning of the railroad. The different colour tracks don't overlap.
So, TransSib: Grey 5, Brown 4, Natural 3, White 2 comes down to:
1 grey, 1 brown, 1 nat and 2 white tracks = 1 + 2 + 3 + 2*4 = 14
Likewise, St.P in your example has 6 (not 8) grey and 2 brown = (6*1 + 2*2) * 2 = 20

Now the totals don't add up to 57, and I can't see the game situation anymore, but I'm sure we're missing something else (doublers, industry, Kiev?). Anyway this is what I could see from your example. Hope this helps.

I Had the same problem with trans Siberian. Ik think the problem is that the revaluation doesn't count correctly.

It's not bug (see Wigbolt's comment). Additionally, you have to consider which tracks your locomotives actually reach.

St Petersburg shows 42 points.

But I do have the doubler for brown 3 points and beige 6 points and white 10 points (in the german rules it says that this count for the tableaut and not only for transsiberian!).
And I reached with the grey the field eight. And the loc activates field 7. So double (x2) points of the track.
So Grey at 8, Brown at 4, beige at 2
I thought it is then (only counted the colourful fields - not until the beginning - I added the steps to see it :-) )
beige (6+6) x 2 = 24
brown (3+3) x 2 = 12
grey (1+1+1+1) x 2 = 8
made in sum 44.

It is not about the 2 points - it is about the logic, because you plan with the rules your scores, aren't you?

Perhaps as additional hint you could make a possibility to see the detail points of each track? Helps a lot of players, I think.

Thank you for all your work :-)

I came here for the same reason - for this game: boardgamearena.com/3/russianrailroads?table=286458190#

I now see though that the tracks don't overlap and so the scoring was done according the scoring section of the rules here: www.ultraboardgames.com/russian-railroads/game-rules.php "Scoring the 3 railroads" . I just hadn't looked at the scores that closely before.

Table #356257552

I ran into this issue as well. I feel like the issue is specific to the Trans Siberian Rail track at the top.
