Project ALEX(Automatic LX)
New Level Crossing
Control System
Housing prototype April 2016
2 2016-04-28
• Training Center personnel are
assembling the prototype
• The prototype is used to
– Optimize space
– Dimension of the batteries
– Find interface requirements
– Receive feedback from maintenance
personnel and suppliers
• During the tender period, a transQ
(category 1.3.5 Level Crossing)
qualified supplier can make an
appointment for a closer look at the
prototype
A housing prototype is built at the
Railway Training CenterALEX is one of several
possible modules
3 2016-04-28
• Housing prototype
– 8 industrial outdoor cabinets
• standard 19 inch racks
• 1.20 m high incl. socket
• 0.80 m wide
• 0.60 m deep
• All cabinets are equipped with
230 V AC outlet for hand tools and
task lighting
– 3 types of boxes for manual operation
• The prototype is an example of housing
to display the needs and requirements
• Opening and closing of cabinets and
boxes are logged by ALEX and monitored
by the Access Control System (TF+SD).
Switches for access control are visible in
photos of boxes.
Overview
An example of assembly
4 2016-04-28
• The prototype
– Equipped to handle two tracks
– Some components are missing, see the comments for each cabinet/box
– Only a small number of cables are routed
• The LX control system supplier will be responsible for
– The housing
– Assembly of all components in the housing, unless other component contracts
prevent this
– Delivery to pilot LX sites
– Installation of housing at pilot LX sites
• Trafikverket will be responsible for
– Installation of external objects at pilot LX sites
• All information is subject to change before the RFQ is released
• Trafikverket is still in a silent period regarding ALEX and is unable to
answer any questions
