Does i need IRJ's on the V's of a double slip?

Mainly electro frog for turn outs I wasn't sure due to he IRJ's on the 4 V's of he double slip and the block isolated to the left of the DS

Thanks for clarifying double slip Andy What do you reckon with he proposed wiring?

Hi guys, I wonder if someone can advise me on the wiring to a series of points, including a Peco 4 Way point? Image attached, I think most of the suggestions detailed are fine, but no sure the 4 Way point wiring is correct. Any help or suggestions are really appreciated. Click image to enlarge it

I found the wiring error! I plotted above the layout, distance from the left cm, distance from the wall cm. Then with the board uplifted I plotted beneath the layout, three/four times I checked and didn't find the error, everything seemed fine, than I found the issue, I had two pairs of wires with similar references. I had noted a location 66/64R (cm), but there was also one 64/66R they were crossed MOVING ON (Board-1 only at this stage) I have two long blocks outer track (one the reverse loop block) One reverse loop block on the inner track, via turn outs, to three separate blocks. Image of this board at top of this page. TEST-1 A loco was run from the reverse loop block to the adjacent block, first the outer track, then the inner tracks. There were no shorts the loco ran perfectly. In every situation the loco ran from the reverse loop block, into the next block and did not release the previous block? Loco length 28cm No carriages or wagons, therefore Train length also 28cm Reverse loop block outer RLB101 - 295cm to SF-P1 - 198cm Reverse loop block inner RLB102 - 180cm to SF-P2 - 140cm Reverse loop block inner RLB102 - 233cm to SF-P3 - 140cm Reverse loop block inner RLB102 - 233cm to SF-P4 - 140cm TEST-2 Return journey from SF-P1,2,3,4 to RLB101 or 02 Before commencing loco moved from SF Block to another distant block then back again, to clear previous block error and get a clean test. In every situation the loco ran correctly and the previous block cleared correctly Loco length 28cm SF-P1 - 198cm to Reverse loop block outer RLB101 - 295cm SF-P2 - 140cm to Reverse loop block inner RLB102 - 180cm SF-P3 - 140cm to Reverse loop block inner RLB102 - 233cm SF-P4 - 140cm to Reverse loop block inner RLB102 - 233cm The good new... - the loco runs block to block without error - iTrain and Digikeijs DR5013 Reverse Loop Module and DR4088LN Feedback's work one way in all situations, but gives the same issue in all situations in the other direction, on inner and outer tracks. The feedback's in both blocks are working correctly, showing and releasing correctly. The only issue now is the previous block not clearing in one direction in all 4 instances? Any ideas guys?

Iain Sorry if I didn't explain clearly earlier, I didn't see the need at this time for the volt meter, because the loco IS running manually without fault. All tests have been carried out with manual loco control. Having had my tea I came out again to run the loco on ALL sections of track on board-1. The loco runs without fault manually operated. I have passed that stage but still have the issues mentioned. The reason I am watching what is happening on screen is that knowing the loco works manually I am expecting what I see on screen to work correctly also, or find an issue and look to fix it, but the faults are not making sense to me. So where am I at now? - loco works manually, no faults, on ALL of board-1 So I look further to narrow down and resolve issues - iTrain works offline, releasing blocks as it should Image of Board-1 The Loco was manually run, backwards and forwards, without error on Blocks SF-P1 to 4 and RL101 & 2 I know you said leave this and get the locos running manually, but I have and they are. Knowing these to are correct I try narrow down the issue - I have removed the loop wiring, plotted every location, left to right and from the wall outwards, then rewired them simplified with just one pair of wires from each track, outer and inner loops. (Blocks) - I have done the same track and trace for the feedback's, to the DR4088LN and to the bus. The problem, seems to me, though I appreciate I am just learning, appears to be between the modules and iTrain, though we know iTrain runs in offline mode as it should. The wiring is as simple as this, track to top of module, out at bottom to DCC Bus, maintaining L & Com in and out as diagram. This is why I am baffled

I will do that Iain Not getting anywhere, I have removed ALL wires to the Reverse Loops. Checked every one, one by one and only replaced 1 pair of wires for each loop. Put loco on RLB101 outer loop, iTrain screen correctly shows, loco in block, block highlighted red and first Feedback light on. Screen and layout match at this stage. Loco leaves block RLB101 and enters block SF-P1 - RLB remains Red (error) - SF-P1 is purple (error) - Feedbacks F18 & F17 in SF-P1 block work fine on screen Reverse the loco from SF-P1 to RLB101 Everything screen and layout set correctly. Loco run in SF-P1 and RLB and feedback are flashing (error) Loco leaves SF-P1 enters Rev Loop Block RLB101 - SF-P1 clears (correct) - SF-P1 feedbacks worked (correct) RLB101 block is Red (correct) RLB Feedback Block is Red (correct) When I tried it again the results were similar but o the return journey the SF-P1 block didn't release (error) Very strange, the loco works fine, there is power to the track I used a track tester for that first. I am only using the two blocks and the rest is not connected to board 2 I tried RLB102 inner also and although the loco ran fine there were more errors similar to those on the outer loop. In theory I am not testing the reverse loop at this point, as I am only using two block and trying to get iTrain on screen to match what is happening on the track. I did wonder whether to take off and re-check the DR5013's Paul

Nope, I purchased a Voltcraft VC820 from Rapid at start but I have never used it, not sure what settings it should be on. All loop system wires now disconnected and hanging from dropper positions, later today I will add them back one by one. Where I have 5 in one reverse loop block and 4 in the other, I will only add one at a time and test each time. Thanks for your help

Hi Iain Done all that, even placed small piece of Imasking tape at each one and visually followed each track length end to end. Plotted ever dropper from above, then double checked every dropper dimension below, logged them in excel and then checked them again. It has to be something simple, something so stupid, stripping reverse loop wires back and starting again seems to make sense now, I am just going over the same ground, over and over again, that doesn't help fault finding either, I will swap the dr5013s round when I rewire them. I have plotted and checked all other droppers also and didn't find a fault. Hopefully the problem will disappear on the rewire of the rev/loops and I don't have to strip them back also. Fingers crossed.

iTrain appears to work fine on the schematic layout. I have plotted all wires and traced them and cannot find the problem. It is so frustrating, this one issue is holding everything up. Tomorrow there is only one thing to do, disconnect all wires one end and rewire again, one by one, within the reverse loops, DR5013's in and out, and DCC Bus connections. Wish me luck guys. I gotta find the problem.

Very helpful Michael thank you.

As I thought thanks I will read the CV's tomorrow and change CV29 Paul

Interesting I ask because I am not sure, which end would you say is the front of this loco? There are two grills on the side in the picture, there is only one grill on the other side. The train driver, piece of plastic, is at the end with just 1 grill, the other end of the loco has the two grills, one each side Bachmann Class 66 (With sound and lights) Thanks in advance Paul

Will do thank you Iain.

Hi, I totally agree regarding the bit of plastic, the train driver, it was more of a comment but your reply made me laugh. Thanks for your help.

Hi Alan, No the loco goes forwards with front lights on, it just goes in reverse in iTrain, but I know iTrain is OK because 8 other locos go forward and backwards correctly. Thanks for your help and the link I will look a after reading the CV's.

I know that iTrain is correct, it also helps knowing that other locos are correct regarding forward and reverse. The loco goes forward with the front lights on so I think the cv29 switch should solve the issue. At this stage the loco is brand new, you know the new I mean, just arrived can't wait to play new. I have not read the CVs so still on address 3, so also not sure which decoder although it is an ESU with sound. I need to read all the messages you guys kindly added, I went away for a brew and came back to more messages that I expected. You guys are very helpful. Thank you.

Hi guys, I have 8 locos that all run forward and reverse correctly. I have just purchased a new Bachmann Class 66 EWS loco, which wants to go reverse when I request forward and visa-versa. The loco has a driver in one end (front) and has lights so front is easily defined. I am aware in iTrain that when the loco is facing forward on the track and the direct arrow on the layout does not match the direction of the loco, that I hold down the shift button and click the track arrow to change its direction to match forward on track and in the loco/train control. But when the track and the train control are both set to forward, the lights on the front turn red and the loco goes the wrong way. Is there a way round this? Is there a CV to change the polarity of the loco? I use iTrain with Digikeijs control DR5000

Wiring error found, thanks for your help.

A little nearer I think but... The first reverse loop is on the inner track of the bottom loop. When the loco is in the reverse loop block the feedback shows as a red box. When I move the loco onto the outer loop, this doesn't happen? The DR5013's are set up as Module 1 and module 2 The inner loop is RLB101 - with address 101 The outer loop is RLB102 - with address 102 Other than the addresses being different the only other difference is Module and module 2. Struggling here? Although the issues are Digikeijs set up of reverse loops, would it help to add a layout file on iTrain?

Thanks Iain Am I best to add 2 feedbacks and 1 block name with length etc, like a normal block? /______F_______Block_____F_____/ Running the 2x F to the DR5013 terminal? At present if I start a loco in block before loop block, it shows an orange line from previous block, through rev.loop block and into next block after the loop, but loco doesn't show progress from one block to another?

I have 4x DR5013 Reverse loop modules, 2 for each end. 2 are connected and wired as per the diagram. When I double click the DR5013 icon, it confirms it is in demo mode? How do I set these up, do I have to disconnect them and register each one, one by one? I am using iTrain 5.0.5 Digikeijs Command Central DR5000 Digikeijs Feed back Modules DR4088LN Digikeijs Reverse Loop modules DR5013

Regarding the loops IRJ__________S__________S_________S_________S___________IRJ I have 4 feeds in the reverse loop length, each join at a cable connector then wired to DR5013. These are 4 supplies within each block, no feedbacks, I take it I don't need feedback on the mimic track? So the mimic track will just show onscreen IRJ__________________BLOCK NAME___________________IRJ Block Name also including description, length, free track and electrified Am I on the right track?

I have 4 DR5013's ready, inner loop and outer loop at both ends. I have simplified the turns from board-1 to board-2 by removing 4 points, his also lengthened the blocks which is also better. So the two tracks on the straight run at the station are 1.8 and 1.9 long, the reverse loop sections are now increased to 1.8 and 2.0m. Standard block length at station to Feedback(s) IRJ________________F____________________IRJ______________F___________________IRJ IRJ________________N____________________________________N___________________IRJ Reverse Loop block section to DR5013 IRJ________________RLa____________________IRJ______________RLb___________________IRJ IRJ________________RLc____________________________________RLd___________________IRJ Wires in Reverse Loop, RLa and RLb together RLc and RLd together Can I still split the Reverse Loop section with IRJ in middle, as I do on standard block lengths? Or do I have to leave the middle IRJ out?

Hi I like to have multiple feeds on a length of track in a block, if I was to have 3 pairs of wires in the loop section, would it be fine to take all 3 blue and 3 yellow wires to a cable connector, then connect the cable connector direct o the DR5013. That would keep the reverse loop feeds the same in the loop section and there should be no conflicts when the reverse feed changes. Hope I am making sense.
