Valley routes avoid such penalties.

Reduced Need for Tunnels andBridges

Building a railway across a mountain range demands extensive tunneling (costly and slow) and high viaducts (locossive to maintain). River valleys bypass many of these obstacles. The Rhine Valley lines, for instance, require only short tunels thurgh spurs of rock, and the bridges are primarily for crossing tributaries, note the main gorge. This drastically lowers construction costs - a critail factor the 19th, and still importantoday whein upgrading existinder corridins.

Pre- Existing Settlement andInfrastructure

River valleys are naturally corridors of human activity. Towns and cities line their banks; roads, canals, and power lines already oversy the e same corridor. A railway that follows a river can therefore connect multiple urban nodes witch minimal additional land difficiention. This also facipates multimodal freight transfers: rail- to -barge terminals ats ports like Duisburg (the medisard 's largett inland port) are only possible because railine run diredirectly thle alongway.
