Abstract
The invention provides a graphical user interface implemented on a computer including an information area for displaying to a user at the computer inspection status information in connection with one or more components of a linear asset infrastructure. The graphical user interface also includes a control component operable by the user at the computer to cause the graphical user interface to display additional information on the one or more components of the linear asset infrastructure.
Claims35
A method for inspecting a railway infrastructure having components selected from the group consisting of track segments and features, the method including:
- a) producing a condition record when an in-field inspection of a first track segment determines that the first track segment manifests a condition that represents a deviation from an operational requirement, the in-field inspection including a visual inspection of track segments of a railway infrastructure, the producing of the condition record including:
- i) rendering a first graphical user interface on a first display of a portable computing device used by an inspector performing the in-field inspection, the graphical user interface having:
- 1) a first data input field configured to receive information identifying the condition observed in connection with the first track segment;
- 2) a second data input field configured to hold information describing a maintenance activity to be performed to rectify the condition observed in connection with the first track segment;
- 3) a third data input field configured to hold information describing a temporary remedial action defining a change in an operational procedure affecting train traffic over the first track segment to be implemented before the maintenance activity to rectify the first condition is completed;
- ii) providing a database for storing condition records and maintenance activity records associated with components of the railway infrastructure that have been identified via in-field inspections as manifesting conditions that represent deviations from the operational requirements of the components;
- iii) electronically transmitting the information in the first and second data input fields to the database and creating in the database a new condition record and a new maintenance activity record in connection with the first track segment at least in part on the basis of the information in the first and second data input fields;
- b) driving a work list indicator in a second graphical user interface rendered on a second display that is remote from the first display on the basis of the maintenance activity records stored in the database, the work list indicator:
- i) showing a list of maintenance activities associated with different components of the railway infrastructure against which condition records have been recorded, the maintenance activities are characterized by respective levels of urgency;
- ii) distinguishing the maintenance activities on the basis of the respective levels of urgency.

A system for managing inspection operations in a railway infrastructure having components selected from the group consisting of track segments and features, the system comprising:
- a) multiple mobile computing devices, each computing device including a display, a CPU, a machine readable storage medium encoded with non-transitory program instructions for execution by the CPU for rendering on the display a graphical user interface, the graphical user interface having:
- i) a first data input field configured to receive information identifying a condition observed by an inspector conducting an in-field inspection of a first track segment, the condition representing a deviation of an operational requirement of the first track segment;
- ii) a second data input field configured to hold information describing a maintenance activity to be performed to address the condition observed in connection with the first track segment;
- iii) a third data input field configured to hold information describing a temporary remedial action defining a change in an operational procedure affecting train traffic over the first track segment to be implemented before the maintenance activity to address the first condition is completed;
- b) a database in wireless communication with the multiple mobile devices for exchanging data with the multiple mobile devices, the database storing condition records and maintenance activity records associated with components of the railway infrastructure that have been identified via in-field inspections as being affected by conditions that represent deviations from the operational requirement of the components, in response to reception of the information in the first and second data input fields wirelessly sent to the database by the mobile computing device creating in the database a new condition record and a new maintenance activity record in connection with the first track segment at least in part on the basis of the information in the first and second data input fields;
- c) a computing apparatus in communication with the database to receive data derived from the maintenance activity records, the computing apparatus having a display, a CPU and a machine readable storage medium encoded with non-transitory program instructions for execution by the CPU of the computing apparatus for:
- (i) rendering a second graphical user interface on the display of the computing apparatus, the second graphical user interface displaying a work list indicator, the work list indicator configured for:
- showing a list of maintenance activities planned to be performed at various locations in the railway infrastructure on different components of the railway infrastructure against which condition records have been recorded by multiple in-field inspections, the maintenance activities being characterized by respective levels of urgency;
- distinguishing the maintenance activities in the list on the basis of the levels of urgency.
