Tallying up exactly how many people ride trains in the greater Tokyo region is difficult due to the proliferation of independent railways, but it’s safe to say that the number rivals the total population of many mid-sized megacities.

这句话算是并列句，"but"前的第一句是一个主系表句型，主语是动名词结构"Tallying up"来做的，后面引出了一个宾语从句---"how many people ride trains in the greater Tokyo region"，宾语从句主语"how many people"，谓语"ride"，宾语"trains"，"in the greater Tokyo region"是地点状语。主句的系词"is"，表语"difficult"，可将"due to..."看成原因状语，"to"为介词，后面接名词"proliferation"，"of independent railways"是其的修饰成分；"but"后的第二部分也是个主系表结构，"it"作为形式主语，系词"is"，真正主语是不定式"to say that"，当然"that"后面还有宾语从句，宾语从句主语"the number"，谓语"rivals"，宾语"the total population"，"of many mid-sized megacities"是宾语的修饰结构。如果把语序变为常规模式，就是"To say that the number rivals the total population of many mid-sized megacities is safe"
