Normal Sudoku rules apply.
For accessibility, lines have been marked with an abbreviation to distinguish them as an alternative to the line's colour.
Cells connected by a pink Renban [RN] line form a set of consecutive digits, in any order, without repeats.
Adjacent digits along a green German Whisper [GW] line must differ by at least 5.
Adjacent digits along an orange Dutch Whisper [DW] line must differ by at least 4.
Box borders divide a blue Region Sum [RS] line into segments with the same sum.
Adjacent digits along a red Parity [PR] line, one digit is odd and the other digit is even.
Large white rounded rectangles are Train Stations. All lines pass through Train stations and may cross over other lines at the Train Station.
Train Stations on the Red Line form a set of consecutive digits. Train Stations on the Blue/Green Line form a set of consecutive digits.
Digits in cells joined by an X sum to 10. Digits in cells joined by a V sum to 5.
Digits in cells joined by a white dot are consecutive.
Not all Xs, Vs or dots are necessarily given.

How is 524816937 not the correct code?
pagedo: @D3M4R - there are 3 incorrect numbers in your solution code. The SudokuPad solution checker will verify that you have an incorrect solution.

Just to be clear, there is only a single line of each type, yes?
The renban one could otherwise work as two separate lines and have a semi-solveable result (it leads to a deadly pair) - where the station is digit A, the top two digits in the centre box are B and C, with the bottom being B...and then the top-left box digits being D and E, and the digits in the bottom-middle and bottom-right boxes being B, C and E.
Or maybe it is two different lines and I've messed up somewhere else when working out that possibility, and there's another reason I've ended up with a deadly pattern!
pagedo: @AdamantChorus - correct 1 single line of each type. I do say "All lines pass through Train Stations ...". I was hoping that info helped with hidden parts of the single lines.

Oh I didn't read the rules since there were common ruleset so I agree I didn't even take "Train stations" in consideration
Still very fun puzzle to solve with a nice use of the RN !

Nice puzzle, TQ.
Unfortunately, I don't understand the train station rule.

Thank you so much for providing the colorblind assistance. Would have been excruciating for me otherwise. Nice puzzle as well!

Fun puzzle, thanks!
Did not need to use the consecutive train station rule.
