В Ябланице останавливается два раза в день поезд Ужице-Врбница и обратный. Если Вы будете в Белграде, то можно обратиться в Wastels. Это агенство рекомендует сайт Seat61.com. Вот что написано на сайте Seat61.com:
Wasteels agency, Belgrade... Recommended!
The Serbian Railways reservation system is linked to the western European railway computer reservation systems, so seat, couchette or sleeper reservations can be made on domestic or international trains starting in Belgrade from most reservation offices or train booking agencies across Europe, including UK European rail booking agencies. In practice however, the computer link sometimes goes down, and in any case agencies outside Serbia can usually only sell full-price 'TCV' tariff tickets, not the various cheap special offer fares that are available locally.
So to pre-book international tickets starting in Belgrade at the cheapest prices, email or call the highly-recommended Mr Popovic at Belgrade station. You can pick up and pay for the reservations/tickets when you get to Belgrade (although you may now be asked for pre-payment). Mr Popovic can also arrange tickets starting in Sofia, if given sufficient notice, for collection in Belgrade. Wasteels contact details are:

Agency representative Mr Popovic speaks excellent English and comes highly recommended. He will be glad to make train reservations for you and book tickets, and even give you advice on visiting Belgrade. Payment must be made in cash in Serbian Dinars which is no problem as there is a bureau de change and an ATM at the station. If you email him in advance he can also make bookings for trains from Sofia. Although the Wasteels office at Belgrade station has closed, Mr Popovic can still be contacted and you can still buy tickets through him, he'll meet you at the station to deliver your tickets.
