After inspecting the construction of the Barcelona Industrial Base, Carlo took a train from Barcelona, passing through Zaragoza, back to the capital, Madrid.
The railway construction in Spain has been quite smooth so far; important cities such as Madrid, Barcelona, Seville, Zaragoza, and Valencia have all been connected by railway. The railway between Madrid and Barcelona even uses a double-track system for greater transport capacity.
Although this increased Spain's railway costs, the results have been quite favorable. Trains depart regularly from Madrid to Barcelona, and after a short wait, trains from Barcelona to Madrid make the return trip.
The train route from Madrid to Barcelona is currently Spain's busiest train route, praised by the Spanish Government as the bridge of economic exchange in Spain.
