Yes Mike I have. First of all thanks for your reply. Second of all. This is my thing, in real life not every turnout has 3 lights in 1 signal head over 3 lights in 1 signal head and not every interlocking has 3 lights in one signal head over three lights in one signal head over 3 lights in 1 signal head. CSX doesn't use lights that they don't have to. For example: Let's say you have a single track starting at signal A and it it splits into 2 tracks at Signal B, one siding and your mainline. And lets also say that this turnout is rated for limited speed. The "Intermediate" or "Distant" signal which is signal A is going to show Approach Limited which is Yellow over a Flashing Green to give a warning that either A. the next signal, signal B, is showing some form of a limited speed aspect whether it be a Limited Approach or Limited Clear or B. that the next signal is showing an Approach. I'll explain more on this in a minute. So lets take example A. You just went through an Approach Limited signal at "A". Your coming up at the "Absolute" or "Home" signal where you see you have a Limited Clear or Limited Approach aspect so you operate accordingly. With that being said, because CSX is starting to get away from using the Advanced Approach and Medium Advanced Approach signal indications in areas that they can. Usually where traffic is more dense and bi-directional running is in place where the speed limit is faster than 45 MPH, such as the area I'm trying to accurately model in South Florida's Palm Beaches where the commuter service Tri-Rail is running along with Amtrak and CSX, they are using Approach Limited to replace Advanced Approach to keep trains moving faster. So what you have now is a signal having 3 lights in the top head and 2 lights on the bottom head with red, yellow, and green in the top head, and red and green in the bottom head. This signal can show these indications... Clear, Approach, Stop, and Approach Limited; or Approach Medium where the bottom green light does not flash. With this being said, CSX is not going to use a double headed, three light in each head signal because it would show and extra indication that is not needed or used and maintenance would be more expensive. Now lets move on to example B. Take my Tri-Rail route for example. In a good section of the route, you have a double track mainline with bi-directional running and the maximum speed limit 79MPH. You have an intermediate signal then a distant signal then your home signal protecting the double crossovers that exist. Now lets say your home signal was showing Stop. Obviously the signal before that, your distant signal, is going to be showing Approach. Well going back to what I said about the Advanced Approach thing is that now your intermediate signal before your distant showing Approach will now show Approach Limited so trains can move just that much faster. Also, your websites version of CSX signals can't show Approach Slow or any Slow speed signal indications. Your websites signals are fantastic, in my mind and for my use they need a lot of tweaking to be able to function like the signals on a real working CSX line. I'm not knocking on anyone because I have studied CSX's signals for years and I work for the railroad. Plus I grew up in south Florida where my route is based. Please reply to this. Give me your feedback. I'd love to post pictures of examples and scenarios. Maybe even help your team of developers come up with some really great signals at that seems to be one of the hardest things to get good quality on in trainz. Thanks for your time. -John
