Development

New Design

An entirely new design railway turnout. Will function in winter conditions without a railway turnout point heater. No high energy bills and no CO2 emission anymore. Because of much troubles and problems every winter with turnouts and turnout-heaters of the Dutch Railways (Nederlandse Spoorwegen) which causes many train-traffic delays, we have developed a new mechanical working principal (a new design) for railway-turnouts during the last 5 years. This new design turnout is not fitted with horizontal movable tongues, and because of that, snow and ice have no impact on the correct working of the turnout ! and because of that it needs NO turnout heating at all ! The problem with horizontal movable tongues (a design of more than 100 years old) is that snow and ice can be falling in between the tongue and the stock-rail. For that you need an expensive and reliable high power turnout-heating (10kW - 15kW) for every turnout which must stay switched-on for two or three months every winter. That will result in high energy- and maintenance bills. Instead of open horizontal movable tongues, this new design turnout is fitted with vertical movable tongues which can slide up and down between four guides which forms a closed box around each tongue. Snow and ice have no chance to fall in or creep in between mechanical parts of the turnout. The vertical movable tongues are driven by a set of short hydraulic cylinders, and are locked in position by mechanical horizontal moving locking bars. The rail-tongues (points) and the locking-bars can be driven electro-mechanically or electro-hydraulically. The winterproof railway turnout will function in winter conditions without a railway turnout point heater. That means : No more train traffic delays in winter because of snow and ice disturbing correct functioning of railway turnouts. That saves much money. No high energy bills and no CO2 emission anymore for the high energy consuming heating systems which must stay working long time in winter periods. (15kW per turnout in some cases) Also disfunctioning heating systems are history now because there are no heating systems needed anymore ! Further there is no need for manufacturing, buying, installing, inspecting, maintaining, repairing and monitoring of heating systems because there are no heating systems needed anymore ! The winterproof railway turnout can replace conventional turnouts which are fitted with a heating system. At this moment the winterproof railway turnout is discussed in The Netherlands with turnout manufacturers : Vossloh Cogifer and Voest Alpine , The Dutch Railways NS and ProRail (the Dutch rail-infrastructure adminstrator) This patented winterproof railway turnout is applicable for both train and tram rail-infrastructure, and will be displayed and demonstrated during the Innotrans at Berlin and the IAF at Munster.

Savings in Euro's, kWh's and CO2emissions

Below a calculation example of the savings which can be achieved with this turnout on one year basis (Deutsche Bahn DB) : Electric Power one point heater : 10kW Amount of heated railway turnouts in Germany : 22567 Average time in 2012 when pointheaters were switched on in Germany : 1440 hours Price for one kWh : Euro 0,07 For producing one kWh 0,7 kg CO2 is emitted. When the Winterproof Railway Turnout will be applied in the DB Netz : • Energy savings each year in Germany : 10kW x 22567 Turnouts x 1440 hours = 324.964.800 kWh • Savings in costs for electricity each year is 324.964.800 kWh x 0,07 Euro = 227.475.36 Euro ! • Savings in CO2-emission each year is 324.964.800 kWh x 0,7 kg = 227.475.360 kg • Further huge saving can be made because DB Netz does not need to purchase, install, inspect, monitor, replace, and repair expensive point heaters anymore. • But the most important : There are no train traffic delays anymore because of malfunctioning turnouts in winter. This turnout will function 100% in winter conditions ! • Serial production of this winterproof railway turnout is not more expensive than conventional turnouts as we use today. It has a very simple mechanical setup.

Demonstrator

One full-functional 1 to 6th stainless steel scale-model is build as a demonstrator for everyone who want to see the whole design work in real during displaying and demonstrating at indoor meetings, exhibitions and technical presentations. This scale-model is a high detailed representation of the real scale winterproof turnout, and can be easily transported because its weight is only 90kg and its dimensions are 1300mm x 900mm. This model is full digital and is programmed and controlled by laptop, and has high power digital servo’s as actuators.

The functional description of the Winterproof Railway Turnout below explains and describes in short how the design works step by step

STEP 1

START POSITION

STEP 1

Red switch-point low, Green switch-point high, and mechanically supported (locked) by the yellow lock-bars which are pushed to the right under the high switch-point (green). Train goes to the left.

STEP 1A

START POSITION

STEP 1A

Red switch-point low, Green switch-point high, and mechanically supported and locked by the yellow lock-bars. The yellow lock-bar itself is locked against moving by the lower red switch-point.

Team Member
STEP 2

STEP 2

When the red switch-point (now low) will be lifted by the hydraulic actuators connected to the red switch point , the yellow lock-bar is unlocked and can be pushed under the red switch point to support (lock) it. When the yellow lock-bar is pushed under the red switch-point, the green switch-point (now high) is no longer supported (locked) by the yellow lock-bar. Now the way is free to pull the green switch-point down by the hydraulic actuators connected to the green switch-point. Simulteaneously the green switch-point will lock-up the yellow lock-bar. Now the yellow lock-bar is locked again against moving horizontally.

STEP 3

STEP 3

All lock-bars (yellow) are connected to eachother by a strip (blue/gray). The strip (blue/gray) is connected to 3 hydraulic actuators (purple). So all lock-bars (yellow) can be moved horizontally simulteaneously by 3 hydraulic actuators (purple).

STEP 4

END POSITION

STEP 4

Green switch-point low, Red switch-point high, and mechanically supported (locked) by the yellow lock-bars which are pushed to the left under the high switch-point (red). Train goes straight forward.
