Yeltech Ltd – Smart Monitoring & Safety Solutions for Rail

Founded in 2004, Yeltech design and manufacture bespoke remote monitoring products; offering practical and cost-effective engineering solutions for an expanding range of industries, Including rail, buildings and structures, water, drainage and environmental management.

Yeltech have developed a range of highly innovative products for the railway industry. Focusing on quality, safety and the customer requirements, Yeltech provides innovative railway solutions bespokely altered to match the markets’/customer requirements. Using wireless data transmission capabilities, we aim to create a seamless transmission from product-to-engineer for maximum monitoring benefits. With our unique, cloud-based system, our products can provide accurate, real-time updates for effective asset management.

YelTemp – Rail Temperature Monitoring Unit

The Rail Temperature Monitoring Unit is an automatic temperature warning system which allows you to monitor the track temperature remotely, without having to go track-side. During periods of high temperatures, the rail can reach up to 20°C above air temperature when in direct sunlight. When exposed to these temperatures, the rail expands and is subject to strong compression. This causes major performance and safety issues for rail operators, as the risk of derailment increases.

The RTMU is Ideal for monitoring temporary critical sites as it is portable, with newly developed features for an easier installation. This largely reduces the need for track-side monitoring and lookouts, saving costs and reducing safety risks.

The RTMU massively decreases the need for manual track side monitoring, saving costs and improving safety.

YelWarning – Emergency Warning Board

Our intelligent smart board is a lightweight Emergency Warning Board (EWB) that is installed next to the track to warn train drivers of temporary speed restrictions.

It has two high powered LEDs mounted on a reflective yellow screen with black chevrons. The EWB has shoulder straps for hands-free carrying and it is the first speed restriction product that allows instant board-to-engineer communication. SMS and/or Email notifications will be sent if the board is knocked over, turned on/off, battery is low (2 days to lights out), or lights have turned off/failed – perfect for track-side maintenance.

Planning is everything for a good proactive maintenance strategy; which in turn, means a huge reduction to costs and speed delays.

YelCharge – Emergency Warning Board Charging Stand

YELCharge is a combined stand and charger for our lightweight Emergency Warning Board. The stand can store up to 4 small and/or large EWBs, ensuring that the smart boards are always available and reliably charged.

They will support faster response times for track-side maintenance. Fully charged EWB’s will aid efficient working practices, ensuring operatives can get to site quickly, maximising productivity.

The stand charger promotes orderly and safe storage systems, that benefit both the products and workplace.

YelWeather – Weather Station

The weather station has been designed and assembled to support the client with the infrastructure maintenance operation at their sites. The purpose of the system is to monitor the ever-changing weather conditions and provide real time data to the operators, via our cloud-based platform.

The actual time data and weather results minimises delays and diminishes areas of risk. Meaning quick and reliable preventative decisions can be made, with full knowledge of current conditions.

The weather station utilises IoT technology resulting in reduced transmission costs, low power requirements and extended battery field life and reducing maintenance costs.


Our uniquely developed web-based platform, YelCloud, is a host for meticulous monitoring data for multiple clients and user accounts. At Yeltech, we have created an intelligent hub for numerous remote monitoring needs using the latest technology and data requirements, allowing users to have diverse autonomous abilities when managing assets.
