Palindrome Sudoku (Daily Sudoku League #46)

I wanted to create a Palindrome Sudoku with a very long palindrome string. After few iterations, I could create this puzzle. I wanted to post this Sudoku for the practice of the 7th Round of the WPF Grand Prix 2014 Sudoku championship, but this puzzle for not tested by that time.
This Palindrome Sudoku is my 46th contribution to The League of Extraordinary Ladies and Gentlemen.

Rules of Palindrome Sudoku

Classic Sudoku Rules apply. Additionally the digits in the squares with the line form palindromes, i.e. they read the same from both the directions.
