Safe and reliable PTC operation

Easy to install and maintain, Trainguard Sentinel comprises of a primary control module and cab display units, with an optional second display. Speed and location are determined via an on-board track database, commercial GPS receiver, and axle tachometers. Trainguard Sentinel also offers integrated head- and end-of-train operation as well as open interfaces to data radios or other locomotive equipment using AAR interoperability standards.

1. Control your trains and improve operations

The gateway to Trainguard Sentinel is a standalone solution that includes an on-board unit (OBU). It delivers speed monitoring, a time-optimized speed proﬁle and a fuel consumption estimate using GPS positioning (or an odometer sensor to determine location for areas without GPS coverage). The system can be expanded with optional brake interfaces and train integrity monitoring by way of head-of-train and end-of-train devices utilizing wireless communication for voice and data.

2. Centralize your control and increase efficiency

In addition to all the features of the standalone solution, the integration of the Operation Control Center (OCC) enables movement authority, temporary speed restrictions, and transparent train position and data. This integration also enables the update and release of locked areas in case of communications failure. It utilizes a double conﬁrmation process that intervenes between the driver and the OCC operator. The locking of areas or deﬁnition of reduced speed areas for track work is also possible.

3. Automate your business to maximize results

In the area of automation, Trainguard Sentinel helps you optimize not only train control processes but also other business operations to reduce cost, minimize inefﬁciencies, and eliminate failures. The optional operations management solution allows the integration of train control into your production and logistics chain, improving the management of both your ﬂeet and staff. Trainguard Sentinel can also be configured for tunnels and underground operations.

Three scalable levels

Siemens Mobility Trainguard Sentinel represents a best-in-class and cost-optimized train control solution. The system is scalable in size and scope, assuring highest operator beneﬁts with the lowest investment costs.
