Why use CLIP?
  • CLIP enables the rapid rebuilding of an OpenTrack infrastructure model.

  • CLIP greatly reduces the time to build an OpenTrack model automating the OpenTrack infrastructure model building. CLIP users have reported more than 75% reduction in the time taken to build an OpenTrack model using CLIP compared to other OpenTrack model building methods.

  • There are other options for loading infrastructure into an OpenTrack infrastructure document but they all require much manual working to turn into a fully finished model. For example with IVT format tracks must be loaded one at a time, then manually cut up into the correct lengths and then manually connected to other tracks. CLIP fully automates the model building thus cutting out the manual working and greatly decreasing the model building time.

  • The CLIP input files are very simple and easy to generate. The CLIP input files can be either created in Microsoft Excel by hand or by writing a macro to convert proprietary data formats into the simple CLIP format to speed things up even more.

  • With CLIP a piece of OpenTrack model data such as gradients, curves, speeds or signal positions can be modified and reloaded into CLIP without disturbing the rest of the OpenTrack model. For example if someone were to build a large model in which they accidently entered all grades as percentages instead of the OpenTrack required per mille: with a CLIP built OpenTrack model you could change out all gradients for the different ones and rebuild the entire model with the different grades in minutes instead of weeks.

  • CLIP enables the rapid shifting of loop locations and other infrastructure. For example someone doing a green field study trying to determine optimum loop spacing for a single track line can test different options by rapidly rebuilding the different options infrastructure.

  • CLIP’s automatic route and path generation feature can if desired only generated routes and paths for one direction of a particular track (thus cutting down on unnecessary route generation). Also with CLIP automatically generated routes will not jump to the other track and back again at a set of closely connected crossovers.

  • CLIP builds all overlaps either from a specified distance from all signals or from a file specifying between which signal and which IRJ each overlap runs. CLIP also connects overlaps to routes. When building paths CLIP chooses the route with the correct overlap.
