Hydrostatic Drive
For enhanced traction and braking, a hydrostatic drive solution is available. This system utilises a through-drive axle and a centrally mounted gearbox, offering superior handling of curves and minimising flange wear. The stub axle system keeps wheel loads independent of drive loads, maximising lifespan and reliability. Operators can select from various drive modes—work, travel, and creep—to adapt to different operating conditions, thereby increasing productivity and reducing workload.
Friction Drive
The Rail Raider Mk2 is equipped with a friction drive type 9b rail axle, driven by the machine's tyres. This system features direct rail wheel braking, along with independent park and service brake callipers, ensuring optimal stopping performance. The design emphasises ease of maintenance, reducing service durations and frequency
Control Systems
AJH's control system utilises an IFM visual display which can be programmed to control multiple features of the machine.
Work Modes
User-selectable modes allow tuning of the system when travelling, working or fine control is required.
Bucket Diverter
Allows the user to seamlessly control hydraulic diversion for different machine attachments.
Trailer Air Brake
The compressor and brake control system is seamlessly managed to ensure optimal performance and minimise power consumption when operating air-brake trailers.
Control Systems
Steering Locks
Our machines are fitted with a steering lock safety system to prevent the steering of the road axles when the rails are engaged, keeping the machine within gauge.
Rail Axle Deployment
Through the control system, the rail axles can be deployed individually for complete control.
Rail Axle Brake Test
For improved confidence, our safety system is available with a brake test function when working on rail (Only available for hydrostatic rail axles)
InTeEx
The InTeEx Rail Rated Capacity Indicator (RCI) System is a cutting-edge safety solution explicitly designed for road-rail excavators, ensuring safe and efficient lifting operations in railway environments. This system provides real-time monitoring of load capacities, machine stability, and operational parameters, preventing overloading and reducing the risk of tipping or structural strain. With an intuitive interface, the InTeEx Rail RCI system delivers precise weight calculations and audible and visual alerts when approaching operational limits. Its seamless integration with the machine’s hydraulics allows for automatic intervention, ensuring compliance with industry safety standards and Network Rail regulations. Designed for reliability in demanding rail applications, the InTeEx Rail RCI enhances operator confidence and overall project safety.
GKD
The GKD Rail Rated Capacity Indicator (RCI) System is an advanced safety and control solution designed to enhance the operational efficiency and security of rail-based excavators. This system continuously monitors load weights, machine stability, and operational limits to prevent overloading and unsafe lifting conditions. With real-time data feedback, the GKD RCI provides operators with precise, on-screen alerts and automatic intervention if safety thresholds are exceeded. It integrates seamlessly with the excavator’s hydraulic and electronic systems, ensuring compliance with industry regulations and minimising the risk of accidents. The system is crucial for ensuring optimal performance in railway maintenance, trackside lifting, and infrastructure projects, providing peace of mind to operators and project managers alike.

Machine Applications for the Rail Raider MK2
The Rail Raider MK2 is a compact, high‑performance Road‑Rail Vehicle engineered for exceptional versatility across rail maintenance, inspection, and construction environments. Its lightweight design, rapid deployment capability, and impressive lifting and hydraulic performance make it a reliable solution for worksites requiring agility, precision, and robust on‑track capability.
Rail Maintenance & Renewal Operations
The Rail Raider MK2 is designed to excel in day‑to‑day rail maintenance tasks, offering the perfect balance of manoeuvrability and capability.
Key applications include:
- Track maintenance — Sleeper handling, ballast work, drainage tasks, and general track repairs.
- Rail renewal support — Assisting with rail removal and installation, supporting renewal trains, and handling small‑to‑medium components.
- Lineside maintenance — Vegetation clearance, embankment works, and ditching operations.
- Switch & crossing tasks — Precision lifting and placement of S&C components in confined areas.
Its compact footprint allows it to operate where larger RRVs cannot, making it ideal for busy or restricted rail corridors.
Construction & Civil Engineering Applications
Despite its compact size, the Rail Raider MK2 delivers strong hydraulic performance suitable for a wide range of construction support tasks:
- Earthworks — Small‑scale excavation, trenching, grading, and site preparation.
- Material handling — Lifting pipes, beams, and structural components with precision.
- Utility installation — Cable laying, duct installation, drainage construction, and foundation works.
- Site access support — Providing a stable platform for personnel working on lineside structures.
Its ability to transition between rail and civil works makes it ideal for multi‑discipline projects.
Specialist Road‑Rail (RRV) Operations
The Rail Raider MK2 is engineered for seamless road‑to‑rail transition, enabling rapid deployment and flexible movement along the track.
Specialist applications include:
- Rapid response operations — Quickly reaching fault locations or emergency worksites.
- Confined‑space operation — Navigating tunnels, narrow corridors, and restricted access zones.
- Precision positioning — Ideal for tasks requiring fine control and accurate placement.
- Support for larger RRVs — Transporting tools, assisting with setup, and providing supplementary capability.
Its lightweight design reduces track loading, making it suitable for sensitive infrastructure or temporary worksites.
Attachment Compatibility & Multi‑Function Use
The Rail Raider MK2 supports a wide range of attachments, enabling it to adapt to multiple operational roles:
- Hydraulic tools — Breakers, cutters, and compact work tools.
- Brushes and vegetation heads — For lineside clearance and brushing.
- Material handling attachments — Small grabs, clamps, and lifting aids.
- Inspection equipment — Cameras, sensors, and measurement tools.
This versatility allows the Rail Raider MK2 to switch roles quickly, improving productivity across multi‑discipline rail projects.
Digital & Operational Integration
The Rail Raider MK2 can be integrated with modern fleet and operational systems to enhance oversight and efficiency:
