Lidingöbanan 7 - Parkvägen

The stop after Centralvägen was Parkvägen.  This was, in my opinion, the most picturesque station on the line, surrounded by trees and greenery with a classic Lidingöbanan station house on platform 1.  (That's why I've taken so many pictures of it!)

Here are some views of Parkvägen both before and after it was closed, starting with a sequence of six photos I took on 21 May 2000.


Parkvägen, platforms and station building

The station building and both platforms, with waiting passengers.  The right-hand platform is used for southbound (toward Ropsten) trains, and the left-hand platform for northbound (toward Gåshaga) trains.
At both ends of the station, the two tracks converge to a single one.


Parkvägen, train approaching from Kottla

Taken from the same position as the first shot, but in the opposite direction.  A train is approaching from Kottla.  If you look carefully at the switch, you can see that the points are in the correct position for the train to enter Parkvägen on the track to its right (see the previous picture).  It will then stop at the platform and open its doors on the right.
The switch above is a spring switch, which is a type of trailable switch.  A trailable switch is one whose points can be moved, in the trailing direction, by the wheels of a passing train.  A spring switch is a special type of trailable switch with a hydraulic mechanism that sloooowly returns the switch points to their original position after the switch has been trailed.  Lidingöbanan uses this type of switch extensively to see to it that trains always come in on the same track at a given station.

More detail for those who want it:
In the picture above, the approaching train enters the switch in the facing direction and comes in on track 1 (southbound trains always use track 1) at Parkvägen.  A northbound train leaving Parkvägen, coming from behind us in the picture above, would be on track 2, the right-hand track in the picture, and would trail the switch.  If the switch didn't return to its original position, a southbound train approaching Parkvägen like the one shown above would come in on track 2, which is the wrong track for that train.  So the switch will slowly return to the position that takes a southbound train in on track 1.
In reality, if the switch failed to return to its original position and lock in that position, the signal for entrance to Parkvägen here (barely visible in the picture above, a shorter metal pole to the right of the track, in the curve, with a black plate at its top) would be red.
Almost all of Lidingöbanan's stations use this principle to get trains in and out on the correct platforms.  The only exceptions are Ropsten, Torsvik (south end; the north end uses a spring switch), Baggeby and Aga, all of which use non-trailable motorized switches.  Another implication of this is that, except for the arrangement at Ropsten requiring the driver to press a button to request a route to Torsvik, all the switches and signals work automatically; normal traffic movements require no intervention by the control center unless there is a problem on the line.  Movements into and out of the depot do require control center intervention, though.  The boxes at Ropsten control the switches at that station as well as the switch at the south end of Torsvik; the motorized switches at Baggeby and Aga move into the correct positions automatically as routes are (automatically) set for normal traffic movements.


Parkvägen, southbound train entering station

The same train entering Parkvägen.  This photo shows the signal a little more clearly.
Car 611, running at the front of this train, is a driving trailer; i.e., it has driving controls but no motors.  The pantograph seen in the photograph belongs to the motor that's at the Gåshaga end of the train.  This is the normal two-car configuration on Lidingöbanan; a three-car train normally consists of a two-car train with a second motor coupled at the Ropsten end, giving a motor-driving trailer-motor consist.
Cars in the 300 series, type designation A30B, are motors.  Cars in the 600 series, type designation B30B, are driving trailers.


Parkvägen, southbound train stopping at station

The same train is coming to a stop at Parkvägen.  Note that its signal is still red.


Parkvägen, southbound train ready to depart

The signal has now turned green, and the train can depart.


Parkvägen, southbound train departing

The train departs Parkvägen.  That guy on the bicycle isn't allowed to ride it on the platform, but I guess he doesn't know that....

More views of Parkvägen:


Parkvägen, signal 41

(23 August 2000)
Signal 41 governed exit from Parkvägen northbound (toward Gåshaga).  Again, as with the views of Brogrenen earlier, note the "S" sign and ATC beacon.


Parkvägen, station building

Parkvägen, southbound train stopped

(23 August 2000)
Parkvägen with a three-car southbound train stopped.


Parkvägen, last day of service

(3 September 2000)
A view of Parkvägen on its last day of service.


Parkvägen demolished, Skärsätra under construction

(12 September 2000)
Yep, that's Parkvägen in ruins.  The sign leaning over at the left is the "S" sign shown next to signal 41 in the picture above.  This photo was taken from the same vantage point as the first photo in the sequence of six above (from 21 May 2000).  When everything is finished, this will be the northern end of Skärsätra station -- i.e., basically just a long switch.


Parkvägen, view toward Kottla

(12 September 2000)
Track replacement being done north of Parkvägen (toward Kottla).  This photo was taken from the same vantage point as the second and third photos in the sequence of six above (from 21 May 2000).
