"Laying track on viaducts is often preferred in China to minimize resettlement and the use of fertile land" I rode across a lot of the country on HSR in 2013 and it was obvious that huge swathes (perhaps most) of the network is on viaducts. Either China is about 40% "physical constraints" (which would make this high speed rail network an even more impressive and our lack of one an even greater failure) or they're actually there to be "nice" (i.e. avoid the need for resettlement/compulsory land purchase).
