Dimitrios Kostopoulos - TRACK-SUPERSTRUCTURE BY P87 STANDARDS

[Dimitris]

MY FIRST MODULE:
I present my PROTO: 87 module, that I have constructed on December 2009 / January 2010. It consists the following:

1./ The infrastructure is made by blue "dow" plastic. However, I need to built the embankment with grass (πρανή με φυτικές γαίες - in greek) by the same material.
2./ The superstructure of tracks with track-parts by BAHNSINN, consists the following:
a./ Ballast form german company "NOCH" in HO size, about 0,02mm. However, the best is from ASOA (http://www.asoa.de). The ballast has "shoulders" (/"μπαγκίνα" in greek)
b./ Laser-cut wooden sleepers (gelaserte Holzschwelle) with distance between sleepers: 650mm in prototype. The sleepers cover a lenght of 30m in prototype (Gleisjoch) = 344,82mm exactly in HO.
c./ Fastenings + rail-plates (Oberbauen + Rippenplatte / Rp) out of cast brass. The fastenings used are the "K"- type (Klemmplatte) of the ex- east and west german federal railways (DB/DR Reichsbahnoberbau). In single-sleepers the Rp16 with one "K" is used, and in double sleepers (where the rails connected / Schienenstoß), the Rp18 with 2 "K"s. I present an example of Rp18 on a double inside slip (D.K.W. / Doppelte Kreuzungs Weiche mit innenliegenden Zungen) in BDZ (Bulgarian State Railways).

d./ Rails Code70 (nickel-silver) presenting exactly the rail-prototype-profil: S49 (49,43kgrs/m) before 1960s. Epoche III. Rails must be CUT and FILED in 344,82mm, such as to cover the length of the sleepers.
The rails are soldered with fishplates (Laschen) out of etched nickel-silver from inner-side of the rails. Then drilled with 0,4mm-holls for 0,4mm-bolts to pass through. The latter are soldered as well, and the excess is cut from the outer-side of the rail. Finally, the fishplates with square bolt-heads out of etched nickel-silver are soldered from the outer side (where the excess of the bolts is removed), and the rails are connected as the prototype. It is very difficult during construction, but I have enjoyed it. The length of the module is 90m in prototype = 1034,483mm in HO, cosnsists of 3 x 30m -track-lengths in prototype = 3 x 344,82mm in HO.
The fastenings of this tracks, where used in GREECE before 1960s not only in OSE (ΟΣΕ), but also in ISAP (ΗΣΑΠ), specially the part where the rails are connected (Schienenstoß). Now, the may be seen in some old abandoned tracks, with either steel /and or wooden sleepers, and in some cases on open Line with concrete sleepers. Nevertheless, the rail-lengths are according to the german standard (15m, 30, 60m), though the fastenings are exactly to the greek standard. The Greek Standard follow the french-system of 18m and 36m - rail-lengths.







a little before the railway station of Katerini, April 2002. Wooden sleepers of type "AZOBE" (Wood from tropical islands / hard) with "K" fastenings (Reichsbahnoberbau) of the ex-DB/DR (German Federal Railways / German East Railways / Deutsche Bundesbahn / Deutsche Reichsbahn).
PROTO: 87 Track Standards



LAYOUT:
The parts of the track-superstructure (Gleisbau), which will be used to each modul of my layout connected, will be the following and they will be constructed according to ΟΣΕ track-superstructure. The track will be single and NOT double, will have at 90% embankments (επιχώματα) and not cuttings (ορύγματα), and will be based on the Northwestern railway axis (Δυτικό Σιδηροδρομικό Άξονα) - Platy-Veroia-Edessa-Ptolemaoida-Kozani & Platy-Veroia-Edessa-Florina:

1./ Sleepers (Schwelle): From either laser-cut wood by BAHNSINN HO /and or plastic sleepers of the steel type with the 'K' fastenings by RST EISENBAHNMODELLBAU HO.
in model

2./ Fastenings & rail-plates (Oberbauen & Rippenplatte): of the 'K' type, either out brass-casting on wooden sleepers by BAHNSINN HO , /and or out of plastic on steel sleepers by RST EISENBAHNMODELLBAU HO.

3./ Rail-profile (Schienenprofil): of the type S49 (49,43kgr/m) = Code70 in 1: 87 scale (HO). In some sections of track, either curved and/or straight the type UIC50 (50,18kgr/m ) = Code75 in 1: 87 scale (HO) may be used (that mostly all of you use), nevertheless not on S & C (Switches & Crossings ) (Weichenanlagen).
in prototype

4./ Jointed-track with fishplates (Schienenstoß): the fishplates out of nickel/silver and the screws out of brass-castings by BAHNSINN HO will be used, as well as the ΟΣΕ prototype for the jointed-track will be used with the german fastening 'K' and the rail-plate-type: Rp16, and NOT the RP18 (that is for double-tracks), as the latter used only in Η.Σ.Α.Π. and still used in BDZ (Bulgarian State Railways) both now on some diverging-tracks. In turnouts (Weichen), when wooden sleepers are used, the joints will have 2 Rp16s (as in straight and curved track) and when steel sleepers will be used, then there won't be a problem, as the greek prototype of joints is the same like the german.

5./ Track- 'shoulders' (μπαγκίνες) & length: shown by the cross-sections (Querschinitte) with green-arrows for wooden-sleeper - track (400mm in prototype = 4,598mm in HO) & with orange-arrows for steel-sleeper - track (300mm in prototype = 3,448mm in HO). The lengths that will be used will be 18m, as ΟΣΕ used the 18m/36m - lengths of the french-system (SNCF), so all my track-lengths (either straight and /or curved) 18m - lenths in prototype = 206,896mm in HO. However, the already constructed-lengths of the german prortype (DB/DR) 0f 30m = 344,827mm will stay as they are and not changed, as it will be a very small section of the layout.

6./ Ballast: it will be the one I use until now, that is the fine exact to prototype: 2cm = 0,23mm in HO from NOCH HO. However ΟΣΕ uses also 6cm = 0,68mm in HO almost white one, which I can get from ASOA HO, when this finished.

This is the work I did till now, and for the first modul (shown in some of my P87 wagon upgrades) an embankment will be constructed as it contains a bridge, as well as wooden base for substructure, and in the second modul containing till now 2 x 30m german sections, in the one side there will be a straight of 18m greek section, and in the side curve of 18m greek section with a radius of 1m = 87m in prototype, as well as a wooden base for substructure. The rest of the single-track moduls constructed will contain 18m lenghts, as menioned before. As my space is very small until now, I will try to complete these 2 moduls, and then if I find space in the future, I will construct the loop I want.

As the curves & the superelevation as well as the turnout type & the station that will be used, will be announced in the next topic.

[Dimitris]

8./ Curves & the superelevation: The radius of curvature will start from 1m (87m in prototype) to 2,184m (190m in prototype), but here will be sections with 2,069m (180m in prototype) and between 1m-1,5m (130m in prototype). The superelevation depends upon the speed in prototype, but in the model will be designed according to ΟΣΕ standards starting from 40mm in prototype = appr. 0,460mm in HO, 90mm in prototype = appr. 1,034mm in HO & 130mm in prototype = appr. 1,494mm in HO - as middle ones & finally 160mm in prototype = 1,839mm, which is the maximum superlevation in ΟΣΕ.

9./ Turnouts & Stations:
- The main type of turnout that will be used, will depend upon the station decided to be constructed, so for straight tracks, will be the EW49 1: 9 R190 either by BAHNSINN HO with wooden sleepers and/ or by RST EISENBAHNMODELLBAU HO with steel sleepers (photos 1 & 2), on which the EW: Einfache Weiche means simple turnout, either left (links) and/ or right (rechts), 1: 9 the crossing-angle = 6,39degrees and R190: the radius of curvature in meters, therefore 190m. This is 99% used by ΟΣΕ in straight tracks. For tracks with curves, i.e. the left section of the railway station of Skydra there is a symmetric contraflexure turnout (A.B.W.: Außen Bogen Weiche) of 1:9 R300.
- The jointed rails of the turnouts, were mentioned in the previous topic for either the wooden and /or the steel sleepers.
- The tunrout switch-rails (Weichenzunge) won't be turnt automatically, but by hand with the manual machine (Riegelhandschloß). Also, all the turnouts will have switch-rails with joints (Gelenkezunge) and not with springs (federzunge), as this is the Greek prototype for either wooden and/ or steel sleepers. However, the prototype has the french switch-rail-profile (SNCF) (pic 3: Elaionas old railway station, 30.12.2012) and not the german one (DB / DR) (pic 4: model pics 5,6: old railway station of Kalamata, 18.10.2014).
- Concerning the crossings (Herzstück / coeur), will be like the one shown (the crossing-nose consisted of parts screwed together with fishplates or not [german prototype]: in the Greek case in some turnouts) in the pics: 7, 8, 9, 10, 11 of the prototype (Elaionas old railway station, 30.12.2012) and model - pic 12.
- Finally, a completed prototype turnout of the type: EW 1: 9 R190 with steel sleepers, would be the one shown in pic 13 of the old railway station of Platamonas in April 2002. As you see it, compared with the model, the check-rails (guard-rails / Radlenker) are exactly the same on both prototype and model, pic 14 & 15, and NOT like the Greek prototype in some turnouts, pics: 16, 17, 18.

I am not sure about which station track-superstructure of this mentioned axis, I will construct, but I am thinking of either Edessa and /or Skydra ones. However, I will have to go there as well to spend a few hours, such as to see which sections of track have wooden sleepers and which steel ones, in either straight and /or turnout track, and the profiles of the swith-rails & the check-rails of turnouts.

I wanted to add to this:
1./ Sleepers (Schwelle): From either laser-cut wood by BAHNSINN HO /and or plastic sleepers of the steel type with the 'K' fastenings by RST EISENBAHNMODELLBAU HO.


That the distance between the middle of the sleepers, will be ONLY for wooden sleepers (BAHNSINN): 650mm for fast lines, 670mm for branch lines, and 700mm for yard ines. Till now the ones I have and constructed their superstructure have 650mm, as they are on open Line. From now I will try to concentrate on 670mm on open Line, and both 670mm and 700mm in stations and yards. This system is the same in ΟΣΕ for wooden sleepers. For steel ones (RST EISENBAHNMODELLBAU), is only 650mm - as a standard distance.

30.11.2014 - Acharnai railway station.

Simple right-hand turnout with steel sleepers with "K" fastenings (E.W.: Einfache Weiche rechts mit Stahlschwellen und "K" Oberbauen)

switch-rails of the turnout. Some simple-turnouts in ΟΣΕ, used the french profile of switch-rails and not the german (as I mentioned in previous posts of this topic). However, in the model, the switch-rails can be easily replaced with SNCF switch-rails from the french CLUB PROTO: 87. Nevertheless, there other simple-turnouts that use the german-profile of switch-rails (i.e. in Platamonas old railway station, as I mentioned in previous posts of this topic), so I definetely use 90% in my layout the german one.

the rest of the parts of the turnout are exactly the same, as the one that Ralph Steinhagen in Germany designs for P87 turnouts, i.e. "K" fastenings + crossings, stock-rails (third pic), etc..Also, in the assembly of the crossings (Herzstücke), fishplates must not be soldered, but ONLY the 0,4mm - bolts to make it look like the prototype of ΟΣΕ.



However, the check-rails (Radlenker) - profile (red arrows) in old turnouts are made by T.M.K. (Τμήμα Μεταλλικών Κατασκευών / Section of Metal Construction, translated from greek), and don't look like the german ones, but there others i.e. in Platamonas old railway station, as I mentioned in previous posts of this topic), that they have the german one, that's why in my trips from now, I will search and photograph all of the diverging-tracks of most of the standard-gauge tracks in ΟΣΕ, and I'll mostly use the common german check-rail profile in the layout, but I can also use in some E.W.s, the T.M.K. profile available from the french CLUB PROTO: 87 - ONLY the rail-profile and NOT its supports, as these are different.

stock-rails of main & diverging routes, respectively

side-1: fastenings & fishplates (Schienenstoß)
side-2: fastenings & fishplates (Schienenstoß)


I like doing trips, and make pictures mainly to the old diverging tracks as they are mostly 90% same to the P87 tracks I and I shall use them in my under-consruction future layout, which they remind me the Epoche IV & V of ΟΣΕ, which I mostly like, mainly the IV (1968/70 - 1991/92).

I like the wooden sleepers a lot, but I crave the steel sleepers, too!

30.11.2014 - Acharnai railway station.

Simple left-hand turnout with wooden sleepers with french "tire-fond (τυρφόνια: as mentioned by the greek railway people working in ΟΣΕ)" fastenings (E.W.: Einfache Weiche links mit Holzschwellen und französichen Oberbauen des Typs: "tire-fond")

This can be handlaid by french wooden laser-cut sleepers + french "tire-fond" + french nickel-silver baseplates + check-rails from the french CLUB PROTO: 87. The fishplates as they are german - shown from the pic - from BAHNSINN HO in Germany.

However, I prefer mostly the german track-superstructure parts based on the fastening type "K", this was the most common in ΟΣΕ standard-gauge tracks.

a wealth of info in here!!! It's going to take me sometime to go through it!
thanks Dimitri, that's a modeler's presentation!

...

[Dimitris]

You welcome my good friend Panagiotis!

Dimitris

[Dimitris]

Thanx to Panagiotis photo from Lianokladi, you may see that ΟΣΕ also used Rp18 (Rippenplatte) german baseplates with "K" fastenings for rail-connections (red arrow) [αμφιδετούμενες σιδηροτροχιές / Schienenstoß] and german PROFILE of switch-rails (blue arrrow).


Many thanx Panagiotis , when I'll go to Lianokladi, I will take many pics of diverging-tracks with old - either german (K) / and or french (tire-fond) - TRACK-SUPERSTRUCTURE.

Dimitris

[Dimitris]

In the rail-joints, it's decided that:

1./ (90-95)% Rp16 (Rippenplatte) baseplates will be used, green arrows.


2./ (5-10)% Rp18 (Rippenplatte) baseplates will be used, red arrows.



cause as I 've mentioned before, most of the rail-joints of ΟΣΕ with the 'K' fastenings with wooden sleepers, have the Rp16 baseplates.


Dimitris

[Dimitris]

Also a photo concentrated on the Rp18 baseplates on rail-joints:
