SPENO SRR 16 M-1 Urban Rail Grinding Train
The SPENO SRR 16 M is a compact 16-stone rail grinding train for metro and tram networks. Published manufacturer material describes work on flat-bottom and grooved rails, open track, turnouts, sharp curves and steep gradients. Model suffixes matter: M-1, M-3 and M-5 are related but not identical configurations.

What is the SPENO SRR 16 M?
The SRR 16 M is SPENO International’s compact rail grinding platform for constrained urban networks. The family combines 16 rotating grinding positions with self-propelled operation, onboard measurement and environmental-control systems.
Manufacturer material positions the SRR 16 M for metro and tram work where curve radius, gradients, tunnels, grooved rail and short maintenance windows make a larger main-line grinding train impractical.
Evidence boundary: public sources identify several SRR 16 M generations. This page uses SRR 16 M-1 for the main model identity, while numeric specifications from Metro de Madrid are clearly labelled as SRR 16 M-3 data.
SRR 16 M-1, M-3 and M-5: what is the difference?
Do not treat dimensions, weight, speed or consumable approval from one suffix as guaranteed for another. Confirm the complete model designation and fleet documentation.

Where is the SPENO SRR 16 M used?
Compact grinding within urban clearances and limited overnight possessions.
Manufacturer material identifies both rail forms for the SRR 16 M family.
The platform is described for plain track as well as switch and turnout areas.
Designed for constrained alignments common to underground and street-running systems.
What technical specifications are publicly available?
The following values describe Metro de Madrid’s E-501 SRR 16 M-3, not every SRR 16 M-1 or M-5. They are included as the most complete public configuration found for the family.
What systems are documented on the SRR 16 M family?
Onboard measurement
Metro documentation identifies measurement equipment and calibration requirements for longitudinal and transverse profile control.
Dust extraction
The M-3 configuration includes a grinding-dust extraction group; reported capacity is 12,000 m³/h.
Fire protection
An onboard autonomous fire-extinguishing system is listed for the Metro de Madrid vehicle.
Turnout capability
Public documentation states that the vehicle can work on switches and other special trackwork.

SPENO SRR 16 M FAQ
What is the SPENO SRR 16 M?
It is a compact 16-stone rail grinding train developed for metro, tram and other constrained rail networks.
Is SRR 16 M-1 the same as SRR 16 M-3?
They belong to the same model family but are different configurations. Numeric M-3 specifications should not be treated as guaranteed M-1 values.
How many grinding stones does it use?
Public Metro documentation describes the SRR 16 Mx family as using 16 rotating grinding stones driven by electric motors.
Can it grind grooved rail and turnouts?
Manufacturer material lists flat-bottom rail, grooved rail, open track and turnouts among SRR 16 M applications.
What is the grinding speed?
The Metro de Madrid SRR 16 M-3 configuration is reported at 2-6 km/h. Confirm the value for other variants.
What grinding wheel is referenced for SRR16M-1?
The site’s catalogue references a 250 × 78 × 150 mm wheel with a published maximum speed of 50 m/s. Machine-specific approval remains required.
Does it include measurement and dust-control systems?
Yes. Public M-3 documentation identifies onboard measurement, grinding-dust extraction and fire-protection systems.
Which SRR 16 M variant is currently listed by SPENO?
SPENO’s current European contracting-fleet list includes SRR 16 M-5 and also lists SRR 16 M among machines offered for sale.
