The Tiefenbach axle counting system (TAZ) was
developed in connection with the proven electronic
double wheel sensor (DSS) for issuing clear and occupied
notifications on station track sections, point switch zones,
line sections and other track clear-occupancy applications.
This provides users in the railway sector, such as rail
authorities, transport enterprises or suppliers of complete
railway safety systems with reliable, safe and low-cost train
position detection and clear notification technology. |
Applications:
- Line-clear notification for station track
sections,
points switch zone protection, bridge section protection,
line
section protection, and approach or island circuit overlays.
- Decentralized points-clear notification
for electrical
locally-set points with switching protection
and
automatic switching from the trailing side.
- Occupied/Cleared notification for
automatic train
operated grade crossing protection systems.
 |
By deliberately using tried and tested components
from the Tiefenbach range of railway technology products, many
operational and technical advantages have been secured for the
user which make the use of this technology attractive even in
areas with simple operational setups, in marshalling yards and
gravity shunting systems, on single-track regional lines as well
as on tram and city railway systems offering local public
transport.

Double wheel sensor (DSS):
Type Application
2N59-1R-200-45 for speeds up to 37 mph
2N59-1R-200-40 for speeds up to 220 mph
2N59-1R-400RE-40 for speeds up to 220 mph with off rail
detection
2N59-1-200-47 for tram wheel sets and speeds up to 44 mph
|
Advantages:
- Maintenance-free sensor technology (double wheel
sensor), unaffected by all known sources of interference
(e.g. traction reverse currents, rail braking,
radio-frequencies etc).
- No electronic evaluation systems required near the
track.
- System functions irrespective of ballast parameters, the
state of the superstructure, axle shunting and weather
conditions.
- Secure detection of all standard wheel-set types, even
for low-floor vehicles.
- Modular construction using Euro plug-in boards therefore
allowing easy expansion and low-cost assembly of complete
clear notification systems with multiple use of components.
- Decentralized, low-cost installation of control systems
in exterior boxes (without climate control!) is possible,
e.g. for decentralized point switch controlling and block
systems in the public transport sector, station control
systems for regional traffic, for grade-crossing safety
systems, or island and approach overlay circuits.
