+Besides the intersection multiplier to count rail piecies, the game multiplies the cost by square root of total rail piece count. The complete formula is:<br />
+<br />
+''Cost = Nt * Ct * sqrt(Na)''<br />
+<br />
+where<br />
+''Nt = rail piece count for given type''<br />
+''Ct = cost factor for given type''<br />
+''sqrt(Na) = square root of total rail piece count (all types)''<br />
+<br />
+When only a single rail type is in use, this can be simplified to ''Cost = C * N^(3/2)''

-Besides the intersection multiplier the game has an algorithm which increases the costs for your network exponentially. ''(If someone can find the algorithm, please insert it here)''<br />

 Here is an example list for the cost increase, with an rough factor to show the cost increase from one row to the next. (Used Maglev rails)<br />
