You can make the "Stack Route" popup activate by selecting an Entry Exit route, say 15E to 4E, then select 14E to 4E - the dialogue box gives you the option to stack the route or not.

Mark,

I'm embarrassed to say I don't recall if I saw your messages or not, but I'd imagine so as the static IP was something I read this morning as part of the troubleshooting. I don't usually steal locomotives as it's almost always just me operating, and my capacity for running more than one locomotive at once is limited, especially if they are doing separate things. The original reason I got into JMRI was that I had no clue what was happening inside my Digitrax command station and there were times that I sincerely doubted that it knew what was happening either; my use of JMRI was to try and get some visibility into what was going on in there.?

Steve,

Regarding locomotives doing separate things: I was just going to try that, and to that end, I was moving a train with a single locomotive in the Zephyr's slot 3, controlled by Engine Driver, out of staging and up the hill. I tacked a second unit, controlled by WiThrottle/slot 1, onto the rear end to act as a manned helper and as the lead unit crested the hill, the whole train came to a stop, even with the rear helper fruitlessly churning away. I went over to the computer to figure out what was going on and was surprised to find that the lead unit was in emergency stop. I pulled the system console and loconet logs. Unfortunately, I'd not timestamped all of the LocoNet logs, only the last three minutes or so. I present them here, truncated and concatenated, with system console messages in bold. I had a total of three old devices attached to the WiThrottle server: two Galaxy S5, each controlling a single locomotive, and a single iPhone 4, again controlling only one locomotive. One of the two Android locomotives was stationary in the yard during this maneuver. I will continue to play around with various devices, and this time have everything timestamped. I hope to have another operator in tomorrow as well. I have the complete system console and a partial loconet log available should you wish to peruse them. I will try the network tool you mentioned as well.

Rummy,

I'm not sure 'signals' and 'sanity' belong together in the same paragraph. <VBG>

1) Signals go at the ends of a controlled block. There may be turnouts at the ends, but not always. There may also be turnouts in the middle of a controlled block with no signals. Also signals may be virtual, not actual hardware. The advantage being that you can purchase 'virtual' signals with imaginary money. For a prototype example just look at an interlocking between multiple main lines. There may be signal bridges at each end of the interlocking, but not normally at each turnout. The signal aspects at the ends will likely indicate the specific route lined through the interlocking. JMRI aspect logic (SML) expects you to enter each detection block and each switch position between signals. There is no limit to the complexity between signals. (don't use SSL, it stands for 'Simplistic Signal Logic' not 'Simple Signal Logic')

2) JMRI SML (Signal Mast Logic) is normally setup as signal pairs. If there are no signals in the reverse direction, then there are no signal pairs in the reverse direction either. JMRI does not know or care about 'direction', so there will be no problem. (except that you will need train orders to run against traffic)

3) Similar signal situations will normally have similar signals. For example a string of passing sidings will normally have the same type of signals at each turnout. (and a mirror image at the opposite end) For signals in one direction only you will possible just have two signal types, one style for intermediate signals, and a second style for signals at a turnout. If by unique signal head you mean the wiring connections, not the style, then yes, each signal will have its own control wiring.

4) The turnout positions are just one piece of information used to determine the signal aspect. Each turnout and each block will independently feed status information to JMRI. JMRI will then determine the proper signal aspect and control the signal. The turnout and occupancy information do not directly control the signals. JMRI logic controls the signals.

Dick :)

Rummy,

1 — Signals are not required at every block boundary. They are normally placed at control points, such as turnouts, and periodically on long main line runs. Most layouts don’t have long main line runs.

2 — If traffic is strictly directional, signals are not required for reverse protection.

3/4 — The hardware is dedicated to a mast. The reference to heads and turnouts implies using something like the SE8C or CMRI to drive the signals. Other interfaces, such as the RR-CirKits SignalMan, can function as a DCC Signal Mast Decoder without defining heads or turnouts.


Dave Sand

I need a sanity check. ?I'm adding signal masts and looking forward to JMRI adding the appropriate logic to make the signals really hum. ?But, I need a few questions answered to be sure I'm proceeding in the right direction.

1) For JMRI to get the logic right, I need signal masts at every block boundary and every turnout? ?

2) And, my layout is a folded doggone with passing sidings and double-ended staging yard, so all traffic will be in a single direction. ?I don't plan on ever running trains on the wrong main, so to speak. ?In order for JMRI to do its logic thing, do I still need signals for both directions?

3) Every signal mast needs unique signal heads, as in each signal head can only be used at 1 location on 1 signal mast? ?Or can signal heads be used in multiple places?

4) Similarly, each signal head needs to have unique turnouts assigned for the aspects?

Thanks, in advance for the help. ?I have a good panel, with contiguous blocks, every piece of track assigned to a block etc. ?And I have created signals (PRR position light style) and placed them on the panel for places I'd like to have signals actually on the layout. ?But there are still block boundaries and turnouts that don't have any signals, virtual or real, and I needed the help to proceed.

Rummy

James,

Dave's method is very straightforward. If you want fine control of the logo location, see my post on this topic on Aug 16

Thanks Dave.? I think I did set that option, but without custom loads.? Going forward, I will consider that load option as it sounds cool.? But for now, I just want to get up and running quickly, and I think this solution will work for me.

I agree - great program!? Thank you to all the developers!

Hi Steve
Clearly it's a display rather than a control issue so that must push it down the pecking order. In my case there is a potential solution by using 2 points rather than a crossover, as I'm only using 2 rather than blocks. A shame as I've only recently moved to showing crossovers instead of points as a neater solution!!

I'm tending to move towards web panel control due to availability of cheap tablets, so anything to make the web and native panels more consistent is good news.

The particular layout that highlighted the problem is a CBUS demonstration layout, so I won't lose too much sleep over it! On that basis, and the fact that no-one else has mentioned it, it might be fair to rate the issue as 'nice to have'.

Hi Sam,
Network issues, particularly intermittent ones, are very hard to diagnose.
The log helps, but unfortunately in this case it only shows symptoms, not cause.
Can you repeat this with multiple devices connected? I'd be very interested if they all lose connection at the "same" time.
My best guess is interference. Something else came online using the wifi. You may be able to see that using a wifi analyzer program. I like this one:?

Gary,
I think you may have missed the comment in my previous post to set the train build option to allow local moves.? This does require a custom load or final destination.? Note that you can create a custom "empty" load, just call it "Empty" or "MT" or whatever and designate it as empty.? If you don't want to use custom loads then your solution of using an additional location works too.? I use all custom loads as I think it adds more realism to the operating session.? It makes more sense to me than delivering a bunch of cars full of "L"!? It is fun to watch an operators expression when they discover that they just picked up a load of political promises from the fertilizer company.

Inspector Dave,? Good to see that you are still around.? It has been a while since we met during an Amtrak station stop in Wisconsin.? I agree with your comments.? He shouldn't need a new location but with Dan's terrific software there are multiple ways to solve almost any problem.? Use what works for you.? The easy way to search for a particular car in the build report on a PC - press and hold the control key then the "F" (for find) key and release.? A window will pop up where you can enter the desired search string - in this case the car number.?

Dave, I don't have the exact wording from the build report available, but it was something to the effect of: the car can't be moved to a destination in the same location.? I think I could get around this with a Final Destination tag or some such, but I didn't want to be too prescriptive in my setup.

Note that my configuration has been a moving target over the life of this thread.? What I didn't appreciate in the beginning was that I wanted my siding to act as both an interchange track and as an overflow track for off-spots.? My first reading of the documentation led me to think that designating the siding as an alternate track for the spurs would serve both functions, but it didn't.? (BTW, the siding is designated as a C/I track.)? I next divided the siding into three logical pieces: -(ALT), -(IN), -(OUT), all in the same location, and I restricted the Destination for cars on -(IN) to be in the current Location.? But when I tried to build the Turn, it would not route cars from -(IN) to the spurs because they were in the same Location (according to the build report).? As soon as I placed -(IN) and -(OUT) in a separate interchange location, it all worked as planned, so I'm happy with the solution.

Is it intentional that the program would not route cars from -(IN) to a spur if they were within the same Location and that Location was the only Destination?

Afternoon -?

Have had some time to run trains last night and this morning and noted an issue with Engine Driver and WiThrottle Server that I can't quite figure out. Basically, the Android device will randomly (?) lose connection to the server. I've read through old threads and tried assigning static IPs to the Androids - the layout computer has had one for ages - and still no resolution. Also tried the basic step of rebooting all involved devices and resetting the Digitrax DCS51 in case it was something on that end. This has been happening on a pair of Androids, both old Galaxy S5 devices that have no SIM card and are in airplane mode continuously. I tried an iPhone with WiThrottle this morning and, while not the same duration, I didn't note any problems. I plan on trying a longer duration test of the iPhone later today.

On the most recent test, I started the WiThrottle server and ran for almost 45 minutes without issue, and then I started having connection problems every minute or two. Sometimes I'd see a message on the engine driver app about trying to reconnect. The console messages - unredacted - are below, starting with the initial connection of a device and continuing through numerous disconnect/reconnect events.
