question about signal placement

[dstelley]

I'm sure its quite un-prototypical the way its set up but I have a small section of track I'm trying to get proper signal placement for.

I'm using JR's signals.

this one section (about a mile in length) has on it 2 legs of a WYE, a diverge to a siding, a converge from an industry as well as the entrance/exits from the mainline.

I'd like it to be protected to the point that only one train can operate on it at a time.

I wish i could draw an easy picture, it'd make more sense...

train approaches the "section" enters the WYE in whichever direction is needed to hit the industry in the proper direction (backing into it). After load/unload it would re-enter the WYE and do whats needed to re-enter the WYE and exit onto mainline driving forward.

Except that an AI controlled train will follow another and foul the WYE, preventing the original train from exiting properly.

Is there a way to prevent all but one trains at a time?

Does this make sense?

It sure makes sense to me, I think.

The AI are wonderful creatures and seem to have a mind of their own. They do some amusing things at times that sometimes require non-prototypical signals.

Try using track marks.

Put a track mark in the middle of the main line on the wye and one way past the wye in either direction. Have all AI trains not taking the wye navigate via those track marks. I had a similar situation where main line trains would take the wye leg because there was a train ahead of them. By forcing them to take the track mark in the middle of the straight part and then the furthest track mark, this forced them to stay on the line they were supposed to.

I also use the absolutely wonderful JR signals. To protect my wyes I use Type 06 or Type 08 signals, lately it's been Type 08s on a rebuilt route They both seem to work and are actually prototypical for the railroad near me. I place signals on each segment with all facing towards the splits, and a signal on each end protecting the entrance to the wye. It's easier to do than to describe.

Overall I have few problems with this. I will note that the Type 08 signals will force the AI to slow down on the main line to 29 mph and then pick up speed on the other side unless you fiddle with the signal control settings. This is done by click on the "?" and setting the signal properties which I never have done.

Hope this helps!

The textbook answer would be to place an absolute signal (for Auran signals, that is, one without a numberboard), at each entrance to the mainline, creating a single signal block for the portion restricted to one train. For the US, signal 04 would be appropriate under the Auran signaling offerings.

This method has been pretty effective for me when multiple trains are navigating to occupy a single signal block. The only issue that arises is that the AI occasionally shifts around who has the green light suddenly, causing a false start and a "passed at danger" for one train. Once this happens there are two trains in the signal block, but they will not collide. Worse case is there is a cornfield meet on the mainline which has to be manually corrected.

I am trying to tutor a newbie to Trainz, and he asks about whether there are pop up instructions, or pop up notices of tasks, or in cab signals displayng a warning of a distant stop signal, for example on the Marias Pass route Amtrak session.

I suddenly realized that when rounding a curve there are teeny corona signals, suddenly displaying a red stop home signal, with no yellow caution distant home signal, it is hard to stop a train going 72mph within that short distance.

There should be a distant home yellow advance signal warning to slow down, as the next signal is red showing stop.

Some places should really have 3 signals in advance of a red home signal.

Is there such a signal that constantly flash's a warning yellow light, to slow down for the distant signal, and home signal, ahead ?
This could be used as a warning that a station stop is ahead, and to slow down.
I found: New Haven Low Dwarf 2 Aspect by Seniorchief that flash's yellow

Greetings to the South Pole! If you incorporate the session rule used in he Mojave route called "Display Cutom HUD," it shows the next signal's status and its distance.

In line with this tutorial it is important to differentiate automatic from absolute signals so as not to confuse the protoge.

There should be a distant home yellow advance signal warning to slow down, as the next signal is red showing stop.

Auran has included many double and triple aspect signals right out of the box since the UTC version or earlier.

Some places should really have 3 signals in advance of a red home signal.

For example, in the US, the 01 signals are triple aspect.

This could be used as a warning that a station stop is ahead, and to slow down.

In fact on the CSX and UP in the USA, flashing red, yellow, and green are advocating more train movement than their solid counterparts. Therefore, solid colors are more conservative.

If you place three 05 or 04 type signals a mile apart, and place rolling stock just behind the mile 3 signal, that signal should show red, mile two yellow, and mile one flashing yellow.

It appears his complaint is with a single aspect signal, if that is the case, he would not use the 04.

The 04 is a single aspect signal, absolute.

Hi everyone..

Network Rail (UK Rail organisation) introduced a new standard signalling distance spacing guide a few years ago for use across the UK rail network to determine correct distances in metres between each block section signal. This guide is what I use on my own route based upon the former prototype branch from March to Wisbech, Cambridgeshire

The distance (in metres) between each signal is determined by both maximum line speed and any gradients on the said section of track..

When creating a session I always add the rule 'Display Custom HUD'. The custom HUD provides an indication of the next signal (e.g. colour) and distance to that signal (same for speed limits). So unless you have placed your signals too close together you have plenty of time to adjust your speed to suit that signal. If you want to signal a station you can always put an invisible signal at the stop end of the platform. Also, you need to watch how you place invisible signals at points as you could run past the main signal on yellow only to find the invisible signal on red outside of the speed limit stopping distance (i.e. if you are travelling on green at 40 mph and the next signal is yellow you should slow to around 20 mph as you pass that signal, meaning that the next signal distance (the red) must allow you sufficient distance to stop from 20 mph.

The proper spacing and placement of the correct signal types, if you are using JR's, should slow you down in time for a red aspect. A red aspect should not just pop up on it's own.
