I’m all in favour of rails, but one important caveat is that units must never be allowed to rail into combat. It took time to disembark, reorganize and move up to the front from railheads. Rail, movement should be used to reinforce areas where you’re not attacking this turn. But should Berlin be allowed to reinforce Baghdad? http://www.decolonizing.ps/site/wp-content/uploads/2012/05/ottoman_empire_1914.jpg
