Yes, but sometimes the costs external to IT aren't always factored in to such decisions, particularly "soft costs" like employee time, unless it were brought up by senior management, particularly the CFO, outside IT. It doesn't always make sense, and isn't limited to Amtrak IT by a long shot. Costs of handling by train crews, for example, including pouching and getting the tickets to the accounting office, aren't incurred by the IT cost center and won't necessarily be looked at by IT unless it were part of a bigger issue. It depends on whose ox (cost center) is being gored. If the costs are great enough for the Finance Department to notice it, in a way that looks directly attributable to paper value tickets, and they made an issue of it, it might happen. One of the big issues is making the "soft costs" attributable. If you could say on average train crews spend 15 minutes per trip handling paper tickets, you might make a case. If they are spending 3 minutes every 10th trip on average, it would be hard to even quantify and even the time and cost to quantify it might not be seen as worthwhile. Until then, the directly attributable hard costs would be the main determining factor, and those are pretty much the hardware infrastructure.There's also the cost of training personnel to use the existing system, and the cost of handling mailed-in refunds. There may be other operational costs, such as handling of the paper tickets by train crew and whatever happens to them after they've been handed off by the train crew.
Been there, done that.
