The Algerian train company is named SNTF, tickets can be bought at the Train stations, unfortunately the website hasn't been updated since 2008 and online booking is not possible any more, time tables are subject to change; the best way is to ask for information at the train station itself. The network in the north is dense. You can reach Algeria by train from Tunisia, although you will have to change the train at the border post. All border points with Morocco are currently closed.
If you can try to catch the newer trains they are more comfortable and climate-controlled.
The realistic and most secure way to reach Algeria by car is across the Tunisian border.The Mauritanian and Malian borders present some security problems, and the Moroccan border is closed.
If you want to get into Algeria from Niger or from the Tozeur border post in southern Tunisia, you'll have to contract an official guide to accompany you across the Saharan routes; otherwise, police will not allow you to get into Algeria with your car.There are no problems if you want to get into Algeria from the Tunisian border posts in the north. As of November 2014 the border to Morocco is still closed and not scheduled to open any time soon.
