If they aren't going to build Z because it isn't in the budget then they should still have to build it and pay for it themselves. I thought that was one of the supposed benefits of the PPP?
The cost isn't necessarily the biggest issue. It's more of an issue with how long it would take to implement. The reality is, for the features included in the contract it would take a significant amount of time to develop the software to control the LED logos. Not to mention the only good way that they could test it would be to have a large number of vehicles running up and down the entire line. Controlling the brightness of the lighting in a way that doesn't cause sudden, drastic changes in brightness isn't as simple as the binary logic that powers the "NO TURN TRAIN" signals that are popping up all over the line. Those signals use a simple binary logic like "Does a train occupy this block?" whereas controlling the brightness smoothly would be more of "Where is the next train? How far away is that train (x)? This station is y units away from the previous station. b = (x / y) * 100. if b < minBrightness then b = minBrightness . Set brightness at this station to b %. Repeat."
