STOP AND BRAKE MARKERS

hello i am new to this forum so please bare with me as i may be in the wrong place

does any one know how to speed profile and brake test with train controller i have the gold version

reason i ask is my train dont stop at the same point with any of the stop markers they are somtimes ok and most times 6 to 8 inches out
can any one help please

Hi Alan,i can't help you with your question but i would also introduce yourself in the new members section.

Hi Alan

I'll have to copy and paste the process from my forum, so it could take a little while.  Bear with me.

John Dew can probably do it out of his head.  If he's along sooner than I can get to it.

Now for the Brake compensation.



This time I selected "Test of the brake compensation with occupancy  sensors" from the drop down menu.  This greys out the Run-Out and the  Pause and leaves the Length still showing the length of the Profile  block.

 CHANGE THIS TO SHOW THE DISTANCE YOU WANT FOR THE  BRAKE TEST. THIS SHOULD GENERALLY BE THE RAMP DISTANCE THAT YOU  TYPICALLY USE FOR THE LOCO THAT IS BEING PROFILED/TESTED

Note: When you have finished testing remember to change the length  back to the block length……failure to do this will give "unexpected  results" next time you profile ( JD)

The default Brake compensation defaults to 0. John  Dew: It is not uncommon for a loco to stop on the test marker without  having to adjust the brake compensation……however since V8 a value of  0 for Brake Compensation provokes an error message in Dr Railroad  To  avoid this its better to enter a nominal value of 1.  The bigger the number the shorter stopping distance.

Very occasionally the loco will stop short of the test marker with the  Brake Compensation set at 0. The work around is to reduce the contact  spot distance…..less than ideal but it effective nevertheless

"Internal" shows a number, and then whether the loco is going forward or backwards.

Use this number to get a fine adjustment of the actual speed, as when  the loco starts off it will default to a different speed.  For example,  an internal number of 120 will result in at track speed of 9 km/h, while  the next internal (160), will result in 12 km/h.

I'm using 10 km/h, so the internal will be 120 (9 km/h), which is the closest.

I put an orange marker at the beginning of the middle Profiling Block,  and a yellow one 30 cm along from it.  Then I moved the blue throttle  slider until it had preset the speed in the box on the right to 10  s.km/h.



Once you have moved the blue slider, the Start button becomes active and  the loco moves along the Run-Out track.  Once it enters the middle  Block, it slows down and stops at the yellow marker.  Increasing the  Brake Compensation makes it stop shorter and decreasing it makes it stop  longer.

The brake compensation is only truly effective at the speed and distance  used in the test so it is important to enter a speed and distance that  will most typically be used by that loco on the layout



Thanks to John for his editing.

It was easier to find than I expected. 

I hope that helps, Alan.

thanks Max for all the help you have put there for me

but thats exactly how i do my profiling and i still have the problem
i wonder if its something to do with the sensors

OK  Then can you describe how your Blocks are detected, Alan?

i use the digtrax system
i have a db150 6 bdl168's and a pm42 all wired for home wiring all the sensors work and light up when occupied so i know they all work
thanks Alan

I'm not much use to you as I have all Lenz right through.  It looks OK though.

We need to find someone with Digitrax, so maybe ask your question on the RR&Co forum, as I don't think anyone here has it.

The other thing you can do is .zip your file and attach it to a reply here.

When you do, I'll ping John Dew.  He can download it and have a look at it on his simulator.

You could also attach it to your question on the RR&Co forum.

MY LAY OUT
THE PROFILING TRACK IS WHERE THE GREEN LINE IS BLOCK IN1

Hi Alan,if possible put any photos in the gallery as attachments take up much needed bandwidth.

Kevin

I am looking at your file right now………which are the most troublesome locos please?

Hi Kevin

When profiling using block Ini 1  which is the start block and which is the run off block?

I think there may be issues with your profiling track but more importantly I think your problems could be related to the way you are setting up stop and brake markers within blocks.

Could you tell me the name of just one schedule where the loco doesnt stop as intended and I will run it here with the simulator

If you can tell me the loco(s) you use and the average error distance ( for example "stops about 6" short") that would be a big help

Regards


John

the block before the green line and before in 1
if you open up a speed profile it will say new start new middle and new end
the sensor for the start is in the block before in 1  the middle and end is in (in 1)
all the blocks are joined on the layout they just look apart on the diagram switchboard

thanks Alan

You can ignore this…..I dashed it off when you were on line

basically all the stop markers don't stop any trains where they are suppose to sometime they do and sometimes they don't thats my problem that i posted

i can do a run and the loco will stop at the stop marker and the next time it may be 6 inches either way
i need the to stop at the markers for my kadee s to uncouple  so 1 inch either way would be great but 6 inches out is no good
its doing my head in now   
thanks for taking the time to have a look at my problem
thanks alan

My apologies for calling you Kevin:oops:

It seems to me that block In 1 is separated by turnouts at both ends?

This is a quote from Page 124 of the manual

There must not be any “dead gap” between the occupancy sections. That means the track sections must be located close together. Track section “Centre” must begin where the other track sections end and vice versa.

Neither point is detected so there are "dead gaps' between the start block and profile block and run off block

Furthermore the route appears to be curved……ideally all three blocks should be in a straight line.

The gap between the start block and in1 must have a big impact on brake compensation

I do a lot of uncoupling on my layout with Kadee magnets so I do understand the problem

I just wanted a specific schedule so I could demonstrate to you what you are doing wrong with stop markers

Could I use 40 Blue Pullman out as an example?

the blue pullman is a passenger train any of the class 66 or37 or a shunter do the uncoupling and haul the tankers
or use what ever you like really
