If a Renfe licence can be obtained i think this would be one of the most interesting and varied short Spanish routes they could have in the game, you have the beautiful terminal of Alicante, a scenic coastal run between Alicante and Elche with a lot of palm tree plantations, orange tree and olive tree groves, a tunnel section and underground stations in Elche followed by some mountain views and pleasant Mediterranean farmland and a bustling station at Murcia, rolling stock would be DMU units and loco hauled Talgo stock.
Would love to see a Spanish route. That will fit the game so much. Although most players want some mainline High-speed action routes...... In my opinion, it would also be great to put any route with Siemens ES64P 1st gen Eurosprinters, like Spain's Renfe class 252, Greece's OSE class 120 & Portugal's CP Class 5600.
