Many people have pointed out how easy it is to defeat the AI, and how the AI simply is incapable of posing a serious threat to a human player during the endgame. But a fundamental reason for this is the instant speed and the infinite capacity of railroads.
While it might be possible to revamp the Civ roads/railroads, I believe that we may be better off simply getting rid of railroads altogether. More than any other factor, railroads seriously unbalances and distorts the game, and makes the AI's task of invading your home continent simply impossible while making the defense of the home continent entirely easy and worry free.
The reason is simply that with infinite speed, infinite capacity railroads, it is easy to defeat any invasion force that lands on the home continent regardless of deployment or location of military production cities. If an invasion force of 8 units lands near a city and you have have 12 cities each defended by 1 unit, you simply activate each and every unit in all cities, instantly transport them over to the enemy, defeat the enemy force and then instantly transport them back to the original cities, and all of this is done in one turn!
Suppose though that railroads and even roads did not exist at all! If an AI lands near a city defended by 1 unit (or even 2), the AI can definitely take the city. Then the AI can march its 8 unit force and take a few more cities before your home guard can converge on the invaders since it will take some time before your spread out force of one tank in each city can converge on the enemy. Since there are no railroads, the AI might not even need to garrison the cities because even if empty, it will still require some time to reach the cities to take them over. By then those cities might have produced a tank (or two) already for the enemy! And while you have been busy emptying your cities and marching them off to meet the enemy, these cities have now become dangerously vulnerable. Another opportunistic AI sees this and decides now is the time to make it a two front war. Do you now still try to retake those cities leaving yourself weakened for enemy#2? (Remember now you cannot instantaneously defeat enemy force 1 and enemy force 2 in in two turns!)
By simply getting rid of railroads (and even roads), whole new possibilities now present themselves.
1. Deployment of forces for defense
Since it takes time to move units, you have to make decisions about where to concentrate and deploy your home guard. (Assumes of course that it is not possible, say, to mass 10 units in each and every city quickly and easily)
2. Importance of terrain
Despite all this attention to detail concerning movement and defense bonuses of terrain, roads/railroads make it largely irrelevant. Now it matters a great deal.
3. Importance of diplomacy
You've been invaded and are now massing your home guard for counterattack? better make sure another neighboring AI doesn't join the fun before you empty all your units in all your cities to engage the invader!
What a vast improvement in challenge and gameplay if we simply got rid of roads and railroads! Without roads/railroads a mediocre AI could become very challenging indeed!
