![]() In PPP dollars it’s around $10 million per km, but the cost may include items I exclude elsewhere in this post, such as rolling stock. Financial Times reports the cost of the Great Western project at £2.8 billion, covering 258 km of intercity mainline (mostly double-track, some four-track) and what I believe to be 141 km of commuter rail lines in South Wales, working from Wikipedia’s graphic and subtracting the canceled electrification to Swansea. Finding exact cost figures by segment is difficult in most of the country, but there are specific figures in the Great Western. In the UK, the recent electrification project has stalled due to extreme cost overruns. However, a check using general reported French costs (as opposed to a specific project) suggests there is no premium in Israel and New Zealand over France, even though both countries’ urban rail tunneling projects are more expensive than Parisian Metro and RER extensions. Moreover, the examples with concrete costs are all in countries where infrastructure costs are high: the US, Canada, the UK, Israel, New Zealand. Like signaling, electrification usually doesn’t make the industry press, and therefore there are fewer examples than I’d like. Continuing from last week’s post about signaling costs, here is what I’ve found about electrification costs.
