A quick test of creating cant in ORD - not fully satisfied...

LiPeng — Thu, 19 Apr 2018 09:06:32 GMT

I made a quick test in OpenRail Designer with a simple geometry (consists of 2 straight lines and a curve R=900m and transition curves L=80m). This is the parameters before the cant is created:

My questions: (1) Can I change the "Equilibrium constant"? We noramally use a fixed value: 11.8. (2) Is there a setting for rounding the "applied cant" to f.x. 5 mm? This option was in PRT SS2/SS4.

The result of the calculated cant is shown below:

My comments/questions: (1) The unit for cant should be mm (not cm). And it'll be great if the unit is only shown in the title line and not in every cell (it'll make it easy when exporting to f.x. excel). (2) Can I show the result with fixed decimals? (3) how do I rearrange the order of the fields?

Thank you!

Turnout placed in a curve

Aleksandar — Fri, 02 Sep 2016 12:52:34 GMT

Turnout placed in a curve changes the length of circular curve element of the turnout.

This is inaccuracy in the elements. Sometimes appears parasite elements.

I think this should be revised!

Anyone else ?

Turnout Definitions in ORLD

Alastair Hume — Thu, 14 Jun 2018 13:14:03 GMT

All

Finally got my hands on ORLD CE 10.06.00.36 (but I think the newest release ends with 42)

Really simple question - how can I define turnouts. Our turnout definitions are currently in XML, so the first step is to be able to convert the XMl to feature definitions for use with the new software - no idea how to do this :)

Second thing is, I have some custom turnouts that I decided to define manually in the software, but for some reason I cannot show the turnout branch tab in the turnout properties. see attached image.

What am I doing wrong?

Would appreciate any help

Thanks

Open Rail Designer - multiple element regression analysis?

Damian Rypel — Thu, 27 Sep 2018 13:36:26 GMT

Hi,

I'm looking for a tool in Open Rail Designer similar to "multiple element regression analysis" (tool in Power Rail Track). I want to connect two lines in a more complicated way than "spiral - arc - spiral" (for example "spiral - arc - spiral - arc - spiral" or "spiral - arc - arc - spiral". Is there any tool in Open Rail Designer that can do something like this?

Thanks

Plan and Profile Generator

doig86 — Wed, 08 Oct 2014 14:37:44 GMT

Where do i begin with this?

Looking through my course notes, they don's seem to explain what this option does and what default files i should load.

Option create cross section in Power Rail Track v8i (SELECTseries 4)

Ariaan — Mon, 14 Aug 2017 09:33:18 GMT

Hello,

If i look at Evaluation -> Cross section there is no option to create an cross section.

See picture

Do i need a re-install or is there an other option?

I'm using:

Power Rail track v8i (select series 4)
version 08.11.09.845

Normally to make a cross section i use the cross section with corridor modeling.

So not really a big problem but i know in earlier version of Rail Track you could create a cross section through the option Evaluation -> Cross section

Best regards,

Ariaan

Equivalent radii calcs

tingleyr — Wed, 01 May 2019 09:03:28 GMT

Morning all

I am working on a project where the client has issued a TXT file for generating required turnouts. I have received a comment sheet stating that the "Equivalent Radii Calculations" are wrong.. Well not necessarily wrong, the project is using German turnouts so have specified German bending requirements. In the UK I gather the equivalent radii formula in BRT is default based on the Swiss way of calculating the geometry.

However, from memory the German way is similar but instead of Rm x R it is Rm x R - T2

What is T.

Slews in ORLD

Alastair Hume — Fri, 29 Mar 2019 18:10:37 GMT

All

Simple one

How do I show slews (both horizontal and vertical ) in OpenRail Designer

Had a look on the learn server and I cant see any videos or resource that shows me how. The only thing I do know is that it can be done - as it is listed in the list of things that are new in the release.

I have a regression line created from right and left hand rails and some geometry that has been regressed.

So my questions would be.

- How do I show horizontal and vertical slews

- Does the geometry have to be created via the Horizontal regression tool in order for the horizontal slews to be displayed

Thanks

Profile tools (ORD) missing

Alex Marina Nelson — Tue, 02 Apr 2019 17:41:50 GMT

Has anyone found profile display tools in Open Roads Designer? Those similar to Create Profile and Annotate Profile in normal Inroads?

I have to display profiles on sta to sta basis to give them to CAD for sheet production, and the profiles have to be displayed with certain symbology, per client's standards.

Then I have to annotate profile, showing top of rail and original ground elevations at 100 ft intervals, track charts data below the profiles- well, all normal railroad stuff.

I have looked through all the tool boxes, watched training videos- nothing at all.

Where is all that?Or plan and profile generator? Live tracking? Are those tools still available, or Bentley developers expect us to submit cute little 3D images with trees and bogus quantities/ estimates that have nothing to do with actual bid items, instead of standard construction documents????

turnout

Abdourahmane Diallo — Thu, 04 Apr 2019 11:53:19 GMT

Hello, As a new beginner in openrail i met another problem with the software, now i'm working in a project using the india railways standards, in the software 1/8.5 BG turnouts are designed with 205,1299m radius, but i want to use a radius of 232m in my turnout design, so where and how can i add my own turnouts characteristics in the turnout library? Thank you.

How to remove readonly access for ALG files in Power Rail Track

NAVEEN BANDARU — Tue, 19 Mar 2019 07:12:05 GMT

Hi all,

I am working with Power Rail Track (V8 SS4), faced issue - with READONLY access for ALG files.

I don't know the exact reason for this issue.

Verified in Project Options > Geometry > Chosen Read & Write in Horizontal Alignment too.

Tried with SAVE AS alg option also but still it is in Readonly access.

Is there any other way to Verify or resolve this Readonly access issue.

Thanks in advance

Track Drainage in SUE

Alastair Hume — Sun, 17 Feb 2019 14:09:20 GMT

What is the current workflow for the laying out and design of track drainage in SUE in OpenRail.

I am quite happy with using the top/bottom 3D cells to create my physical features of the catch basin that I am using. I am also happy with the pipes feature definition and sizes, both in the feature definition and from the catalogue definitions. I can get on board with catchment feature definitions and this all makes sense.

What I cannot work out is how to work with assigning catchment areas to inlets/catchbasins. The way track drainage works is that perforated pipes act as collector pipes. Water percolates through the ballast to the formation, which is laterally sloped to drain into the pipes. These pipes then drain through the catchpits to outfall. The catchpits are placed to allow maintenance, and to allow a small amount of sump storage/attenuation in the network

For track drainage then, while I can assign a catchment areas, there is no associated gutter for defining the hydraulic prototype of the catch basin for design, as the pipes are the collecting medium, which change in length depending on the physical constraints of the network i.e. distance between nodes. So this value is not set for a specific node.

Has anyone got any idea of the best way to undertake this type of design if you are not draining a surface ,but a subsurface using pipes as a collector.

Thanks

ORLD Turnout Annotation

Alastair Hume — Mon, 14 Jan 2019 14:12:22 GMT

I have been working in the Metric Example workspace and have come across a method of annotating turnouts used in the examples delivered with the product.

The attached image below shows a text favourite that is used to annotate turnouts in plan. My question is, how is this text favourite defined? Unlike other text favourites, I cannot click on the shaded fields and interrogate where they come from. The fields look like name, description, ratio, intersection point chainage and toe chainage. However I have no way of knowing.

Is this something to do with item types?

Ideally I would like to create individual text favourites for each of these turnout properties, and then use them within the turnout annotation definitions to put the text where I want it to be in the Turnout.

I am willing to put the work in here to make this operate correctly for our turnouts, however I am reminded of the Network Rail Extension Add In for BRT/PRT and annotation was much simpler for turnouts using this method.

Cell for turnouts

Asmir Kapetanovic — Fri, 11 Jan 2019 12:22:00 GMT

Hi,

Just noticed that we got the option for turnout annotation (as cell) in SS4 ver.904

what I se as a very useful function when there is need to separate the existing from the new turnouts,

but the cell landed with origo on crossings (.0) point in turnout and not on the tip point (.1).

Is that working as designed?

Regards

Asmir

Turnout Bearers in 2D/3D in OpenRail

Alastair Hume — Wed, 05 Dec 2018 12:43:19 GMT

All

Am having a think about the creation of bearer arrangements for turnouts in both PRT SS4 and in OpenRail. My main thoughts are towards using civil cells as sleeper/bearer geometry in order to show the correct arrangement and orientation about the lead rail, that would allow changes if this turnout is in similar or contra flexure. I would like to know Bentleys approach to this in OpenRail in order to focus my efforts.

The current create sleeper tools in OpenRail shows sleeper in turnouts graphically in 3D. However is assumes a constant sleeper arrangement through turnouts, which is not the case in the UK as turnout sleepers are defined as per manufacturers drawings, and are more complex than stating a spacing/centres, with a linear change from origin to last long sleeper, which is what I assume OpenRail does at this point.

I would like to suggest an improvement to OpenRail that allows the sleeper alignment to be defined in the DGNLIB that holds the turnout information, making a note that this is defined about the lead rail - which is a half gauge offset from the CL of the track (maintain length along inside rail to IP in SS4 turnout library file). This would mean that if the turnout is curved, then the sleepers would be orientated correctly. Kivanch if you are involved in thinking about turnouts, and this is something that could be developed, and I can help in any way - please let me know

In addition, with regard to my civil cell approach, currently, Civil Cells in SS4 cannot be used in OpenRail, and vice versa. Is this likely to change? I am quite progressed with this, using 2D geometry in civil cells to define how bearers look in turnouts and would like to maintain my resource when we move to OpenRoads.

Would appreciate any help

Thanks

Alastair
