SELLA CONTROLS have been working with Kamera & System Technik (KST) for many years to offer the UK rail industry high quality, safety-related specialist CCTV cameras for on board rail vehicles.
Camera and housing applications include Driver Only Operation (DOO), Pantograph surveillance and Front Facing.
The range of cameras housing is many and varied with a range of off the shelf proven units for Metro, Urban and High Speed trains but also bespoke housings can be manufactured to suit individual applications.
High Speed camera housings have been specially designed to optimise the air flow over the camera viewing glass to reduce the effect of dirt and water on the glass.
The EKE-Electronics Trainnet® Human Machine Interfaces (HMI) are interactive displays. They can be used to display information to train drivers or cr
ew members with interactive displays. They can also be used as CCTV monitor as well as for any Trainnet® applications.
The Trainnet® HMI are flexible devices providi
ng ease of use and robustness for all Trainnet® applications.
The touch control buttons positioned around the display area provide great durability with no mechanical part to wear out. The layout of the keys is designed according to the international UIC 557 standard. You can easily configure the keys to match any of your requirements.
The flat displays, including the touch control buttons, are protected behind an anti-reflective vandal proof safety glass (IP 65) for durability.
As the displays are very compact, they can be fitted virtually anywhere in the train and are easy to mount (rear fixing for protection). Two sizes are available for flexibility: 6.5” and 12.1” with respectively 640 x 480 and 1024 x 768 pixel resolutions.
As part of a Trainnet® System, the HMI is usually configured and controlled by the Coach Computer’s CPG (Central Processing unit with Graphics controller). There is a DVI-I interface and a touch screen interface integrated into the same cable.
The Trainnet® HMI also sends self-diagnostics data to the Coach Computer, such as module temperature and the count of lamp’s operating hours. The display does not include any moving parts and the lamp is the only replaceable component. The absence of components that are subject to any wear out guarantees a long unit lifetime.
The Trainnet® HMI 12.1” is available as a full touch (FT) screen as an option. The 12.1″ FT display does not have touch control buttons around the display area.
A Trainnet® Event Recorder (ER) is an on-board data recorder for collecting and storing vital train-borne information. The Trainnet® Event Recorder can record all kinds of data including audio and video streams.
Trainnet® Event Recorders are able to record virtually any available signals, analogue or digital. The Event Recorder can be programmed to record safety critical information like train speed, train position or brake temperature. The Event Recorder can also record video streams from onboard digital video recorders (DVR) or directly from the cameras. For easy data retrieval, the stream format can be made compatible with your CCTV Software or any other video analysis Software that you are using. Alternatively, we can develop customized video analysis tools to fit your needs.
Trainnet® Event Recorders have an Ethernet port, a USB port and an RS-485 port at the front for easy access. The Ethernet port and the USB port can be used to download the data stored in the recorder. Alternatively, the Ethernet port can be used to connect to a sub-system or an Ethernet Switch. The RS-485 port can also be connecting sub-systems.
All the Trainnet® Event Recorders are protected against shocks, vibration, humidity, temperature variations, excessive emissions and excessive voltages (follows the EN50155 standard). Front-panel imprints are available upon request.
Additional interfaces can be easily added to the Event Recorder, as the system is modular. You can add bus interfaces such as MVB, CAN, Serial Links or Ethernet to connect with train sub-systems or Train Communication Network (TCN) in order to acquire data. You can also add Input/Ouput Interfaces to record various signals. Available I/O Interface Modules include Analogue Input, High Speed Analogue Input, Digital Input/Output, Digital Relay Output, Analogue Output and Pt-100 temperature Sensor Input.
Integrated event recorder
For a compact and efficient system, Trainnet® Event Recorder can be used as part of a broader Trainnet® system, for instance integrated to a Gateway, a VCU or a TCMS.
Data retrieval and analysis
Data can be retrieved at any time via the Event Recorder Ethernet port using the Trainnet® TIP Software (Train Inspection Program). The TIP Software enables the download and the analysis of the train data. Alternatively, the data can be transferred to a USB stick, for convenient transport or storage. The data is easily imported from the USB stick to the TIP Software.
The Trainnet® Event Recorder proves useful beyond traditional use following an incident. The retrieved data can be visualized with the Trainnet® TIP Software in order to perform regular system performance analysis and train operational optimization.
Train Control and Management System (TCMS)
The EKE-Electronics Trainnet® Train Control and Management System (TCMS) provides a single point of control over all train sub-systems. The TCMS enables control and monitoring over virtually any sub-system and function, for instance doors, brakes, PIS/PA and video surveillance, to name a few.
Using a unique control and management system allows for a simplified Train Communication Network (TCN). The train architecture becomes more efficient, thus saving on development and maintenance costs. In addition, the centralized TCMS is used to automate train operations and sub-system diagnostics, enabling increased reliability and quicker response times.
The core of the Trainnet® TCMS is the Trainnet® Train Communication Network (TCN). The Trainnet® TCN is the infrastructure enabling the exchange of information throughout the train. It connects all the train sub-systems together via a common network (or several when requested), enabling centralized control.
In practice, the TCN consists of train computers, commonly referred to as Gateways, connected to each other as well as to train sub-systems. Trainnet® Gateways support multiple interface technologies including WTB, MVB, CAN, Serial Links and Ethernet. Please read the TCN and Gateway pages for more detailed information.
The Trainnet® TCMS can be used to automate the train sub-systems. In most modern trains, on-board sub-systems generate a large quantity of data which is essential for safety (speed, braking, faults etc.) and operation purposes (system status, energy consumption, video recording etc.). The Trainnet® TCMS is able to gather this data, analyse it, and send logical commands and warnings. The information can be automatically exchanged between sub-systems and conveyed in real time to the train driver, the train captain, remotely located personnel and even passengers.
The Trainnet® TCMS is a versatile train computer which can be used in number of applications such as:
Automatic Train Inauguration
PIS/PA system management
Crew HMIs management
Brakes and traction monitoring
SIL and Safety Applications
CCTV system management
Tank level monitoring
Battery charge monitoring
Train-to-wayside communication management

Remote Condition Monitoring System (RCMS)
SmartVision™ is a Remote Condition Monitoring System enabling real-time analysis of train data to improve train availability and fleet performance.
The SmartVision™ Remote Condition Monitoring System (RCMS) collects and analyses key data from the train fleets, then provide diagnostic information and appropriate responses, in near real-time. The RCMS automate and rationalize diagnostics and performance data in order to improve train availability, maintenance and the use of resources.
SmartVision™ is a modular system designed to adapt to various fleets and different levels of
needs. It allows you to develop a single remote condition monitoring and diagnostics system across your entire fleets. Using the same system for all your rolling stocks helps you maximize synergies and efficiency while saving time and money.
SmartVision™ can be implemented at three levels:
1. Data acquisition
2. Online monitoring
3. Predictive analytics
All or a part of these three services can be implemented, depending on your needs and current systems.
Selective Door Opening/Correct Side Door Enabling
On-board train control systems play an essential role in safety within modern railway infrastructure; and to a large degree this safety has to be afforded irrespective of the age of the rolling stock and of the stations they serve. Such systems need to meet a variety of operator and regulatory requirements, and one in particular became important with the advent of powered doors.
These reduce the amount of time trains stop at stations and improve passenger safety. However, whether opened by or for passengers, the operating doors must be on the platform side of the train: a requirement that has given rise to the term Correct Side Door Enabling (CSDE). However, it is not simply a case of enabling all doors on one side of the train or the other. Many trains are longer than some of the platforms they serve, and accommodating this has given rise to the term Selective Door Operation (SDO).At a fundamental level, CSDE requires knowledge of which side of the train the platform is on and SDO requires knowledge of how many doors should be opened.
SELLA CONTROLS have been involved in Selective Door Opening systems since the early 1990s and have extensive experience in these applications.
The selection of an SDO and/or CSDE system is dependent on a number of factors such as existing technology already on board the train, route geography and commercial factors.
One of SELLA CONTROLS’ solutions for conveying the knowledge for both is through the wireless transfer of data, from platform to train, using its Tracklink III® product; which was first launched in 1996 and is now in its third generation. Tracklink III® comprises two key elements for the transfer of data, namely: a passive tag for storing data relevant to a platform; and a train-mounted reader for reading that data. The ‘passive’ aspect of the tag relates to the fact that it is a beam-powered Radio Frequency ID (RFID) device. It requires no power cable or batteries.
Another solution for SDO is by the use of an onboard standalone GPS controller with or without a Tracklink III® system. This can also be offered by SELLA CONTROLS
Train Based ASDO and CSDE solutions using Tracklink III® Beacons and interface to Train TCMS
The system has a Tracklink III® Reader mounted in each cab vehicle per unit and communicates to the TCMS via a serial link. Tracklink III® Beacons are mounted at every platform. The Tracklink III® Beacons provide location specific information as per RIS-2795-RST to the TCMS. Based on the TCMS knowing the length of the train and the data on the length of the platform from the Tracklink III® beacon, then the TCMS can enable the correct doors at each platform.

Train Based ASDO and CSDE solutions using Tracklink III® Beacons and interface to Train TCMS with GNSS
The system has a Tracklink III® Reader mounted in each unit and communicates to the TCMS via a serial link. The TCMS is used as the ASDO/CSDE controller and contains a database of the stations on the route. A GNSS geofence for each station and a network route is used so that the train identifies when it is at a particular station. This information is used to provide the SDO functionality for most of the route. Where there are stations with different platform lengths or where there is unreliable GNSS coverage then Tracklink III® Beacons are mounted at each platform of the affected station. At these stations the ASDO system will default to the shortest platform length unless it detects the Tracklink III®beacon, with the information from the beacon the TCMS can then release the full amount of doors for that platform. In the case of the Class 378 then all platforms are fitted with beacons to give CSDE functionality.

Vehicle Based ASDO solution using Tracklink III® Readers and Beacons
Used on older trains where there is no TCMS or train bus that can be used. The system has a Tracklink III® Reader installed in each vehicle and a Tracklink III® beacon installed at the start of each platform on the train routes.
Any vehicle fitted with a Tracklink III® Reader that passes over a Tracklink III® beacon will have its doors enabled, any vehicle that does not pass over the Tracklink III beacon will not have its doors enabled. Interface to the door control circuits is done via outputs in the Tracklink III®Reader.
Reference: Class 458/5.
Train Based ASDO and CSDE solutions using Tracklink III® Beacons and Safety PLC
The system has a Tracklink III® Reader mounted in each cab vehicle and communicates to a safety PLC. Tracklink III® Beacons are mounted at every platform. The Tracklink III® Beacons provide location specific information. The train has to stop over the Tracklink III® Beacons within a tolerance of plus or minus 1M. If stopped in the correct place the Safety PLC enables the correct doors based on the information from the Tracklink III® beacons.
