Although Hot Rails will not specify any power infrastructure, we will include some cost estimates of it here all the same.
AECOM13’s estimates are detailed in the table below; the total cost of $5.2 billion comes to an average of $2.975m/km.
|Modify existing substation||$5m||Each||As needed|
|New transmission substation$50m||Each||As needed|
|Transmission lines||$500k||Per km||As needed|
|OHLE||$1.5m||Per route-km||Entire length|
|Traction power substation||$36.1m||Each||Every 60km|
Von Brown study
Von Brown’s 2011 study broadly supports the estimates of AECOM13, with 354km/h dual track electrical infrastructure coming to $2.125m/km. Note: the data below is per mile. The cost is approximately half for the lower design speed of 125mph (201km/h).
