Your SURname (family name) most likely is correct?

In fact there was even a kind of rule that for first name (common name) only first letter has to be fed in/printed on paper tickets.

Checks on this are very rare-seems also to depend a bit per country on how conductors got instructions, but if it is done, nr of ID/passpt is usually the most importt.

Thanks for your response mcadv,
