Transport
Transport in Portugal is well-developed and diversified. Portugal has a 68,732 km network of roads, of which almost 3,065 km are part of a 44 motorways system.
All motorways are marked with their own symbol and usually charge tolls. Paying the toll in Portugal can be a little bit trickier than expected: on some motorways manual payment is allowed and it is possible to pay toll by cash or credit card, in other cases motorway fees can only be paid automatically through an electronic-only toll point.

Train
The train network connects all the major cities in mainland Portugal including Lisbon, Porto, Aveiro, Coimbra, Faro, and Lagos.
Prices are cheap, but there are also discounts for booking in advance – as much as 65% off for booking 5, 8 or more days in advance on many routes. The cities of Lisbon, Almada and Porto/Gaia have a metro (underground) network that operates between 5/6.30 a.m. and 1/2 a.m.
