Thread: на какое число есть билеты

"Теперь вы можете узнать, какие поезда ходят из Москвы в Ленинград, и на какое число есть билеты."
My doubt is about what is in bold. Does it mean "for which (number of) train there are tickets" or "which number (amount) of tickets there are"? Thank you.

"Число" = day of the month (date).

Thank you for your answer.
