Rail / Surveying / Design

Modules to plan and design rail-bound transport routes.

Point Management

Point management, import and output of points.

Surveying / Surveying (Rail)

You can solve your surveying-related standard tasks using the module Surveying. Besides the interactive graphic evaluation of tacheometric measurements, the module provides all of the important coordinate transformations, the calculation of setting-out values and many more features.

Transformations (DB_REF)

Additional features to directly support the GNTRANS transformation solution in order to  transform project data between the Gauß-Krüger system or ETRS89 and the DB_REF system.

Alignment Design (Rail)

You can design track alignments with rail-specific transition curves, switches and cants on-screen. card_1 supports any existing transition curves and cant gradients. You can design with card_1 anywhere in the world. You need clothoids, Bloss curves and Schramm parabolae in Germany, cosinusoidal curves in Japan, sinusoidal curves to design Maglevs and the curve type Wiener Bogen® to design for the Austrian Federal Railways. Even rarely used radioids, which in certain regions are used to design tram lines, are available.

This module offers excellent features to design private or federal railway routes, including the route design elements required. The guidelines of the German Federal Railways and those of the Austrian Federal Railways are integrated in the system as well as the entire switch library. Switches are automatically calculated, whether they are located in straight sections, in curves or clothoids.

Alignment Drawing / Alignment Drawing (Rail)

You can create complete and technically sound alignment drawings with flexible annotations, carriageway edges and gradient changes. The batch mode enables you to generate multiple drawings in one step.

Alignment drawings may be displayed as a background layer in all base maporiented applications.

Vertical Alignment Design / Vertical Alignment Design (Rail)

Designing and editing vertical alignments is similar to designing alignments, in that you can conveniently design and edit them on-screen taking constraining points into account. The relevant design data is displayed and synchronized in the various views, e.g. longitudinal profile, curvature string and cross-fall string.

In the card_1 system, vertical alignments are height profiles defined using tangent intersection points. They are used not only to describe the vertical profile of roads, railways and sewers, but also as height definitions for swales, ditches, carriageway edges and other alignment-related structures. Individual evaluations or evaluations as lists are integrated in the application.

Vertical Alignment Builder (Rail)

You can generate an optimized vertical alignment (as close as possible to the existing ground profile). When using this module, the program automatically picks the optimum vertical alignment from a large number of variations. Besides the on-screen check the program provides you with a comprehensive report of all input data. You are notified whenever the defined value limits have been exceeded or fall short.

One main field of application is to upgrade and optimize existing track facilities. As the route parameters are not available for all existing routes, this module supports those working on a project by automatically reproducing both the planimetric position and the height of the route from surveyed track facilities.

Profile Drawing / Profile Drawing (Rail)

You can create engineering-grade longitudinal profile drawings with vertical alignments, longitudinal ground profiles, flexible annotations, curvature strings, cant gradient strings, sight distance strings or other strings.

These drawing components can be displayed together with tangent strings, dimensionings, drawing sheet borders and title block fields in a card_1 drawing.

Cross-Section Design / Cross-Section Design (Rail)

You can design and edit cross-sections and surface structure lists in a highly automatic manner with this module. This module is a very versatile tool to work on projects with many special conditions and different guidelines while keeping the planning time and costs to a minimum.

The cross-section designer offers unlimited freedom during the design process, making it possible to turn your ideas into reality. more >

Cross-Section Drawing / Cross-Section Drawing (Rail)

You can create cross-section drawings with individual sheet positioning, flexible annotation and design.

You can display and output surveying vehicles, road and rail furniture objects, trees and hedges. more >

Route Plan

You can use this module to create complete route and track marking plans for single and double-track lines in accordance with the relevant guidelines of the German Federal Railways.

As a special case, it is also possible to generate route plans for double-track lines, from which one of the tracks has been removed. In this case, the remaining track may wander between the left and right side of the sub-grade several times per kilometer.

Switch Elevation Plan

You can use this module to draw complete switch elevation plans including plan and elevational views of track alignments, chainage strings as well as drawing borders with title blocks and legends.

Rail Structures

Generation of 3D objects for rail structures. BIM-compliant attribution.

Point Management DB AG

Coordinates with higher accuracy.

Vehicle Dynamics Check

Check the track geometry according to the applicable guidelines, examine the speeds.


You can use this module to design maglev routes. This module is based on the current card_1 version and offers additional features which are required to design maglev routes.
This module meets all guidelines to design maglev routes as well as the project work guidelines. The maglev route is designed in such a manner that the acceleration and jolt values are not exceeded.

LandXML Export Rail

Export route data in the 7-line model in order to upload to a tacheometer and set out track routes.
