WARR Today :: Completion of Andraca Overbridge

The Andraca overbridge was completed.
It is Suspension Bridge where it is located in the next of the east at the Andraca station, and Park Way is stepped over.
There is 50-meter length of the span in single span Suspension Bridge, and is 13-meter height under the digit.
This is the maximum bridge in the WARR line.

Andraca跨線橋が竣工しました。
Andraca駅の東隣に位置し、Park Wayを跨ぐ吊り橋です。
単径間吊り橋で、径間長50メートル、桁下高13メートルを誇るWARR線最大の橋です。


It is a structure that only the digit in the part placed between two main towers is hung with the cable.
Digits outside in main towers are constructed as a usual truss bridges.

吊り橋の主塔に挟まれた部分の桁だけがケーブルによって吊られている構造です。
主塔の外側は通常のトラス橋として建設されています。


Temporary housing guides are set up.
Non-physical type vehicle can run on this though it is not possible to run in the physical type vehicle because construction for a physical vehicle has not ended yet.

仮設のガイドが設置されています。
物理車両対応工事はまだ済んでいないので、物理型車両は走れませんが非物理型車両は走れます。


When this bridge was constructed, I got large cooperation from Mr.(Ms.) Cedric Brown.
I describe gratitude here.

この橋の建設に際し、Cedric Brown氏に多大なるご協力をいただきました。
ここに感謝の意を述べます。

WARR Today :: Sandgrass Overbridge

The third bridge was completed in the WARR line.
There is Sandgrass Road in the next of the east at the Gunda station in the Gunda region. The bridge to exceed this public road is Sandgrass Overbridge.
This bridge became a type with the feature very much. In the plan at first, it was an ordinary truss bridge. However, the fate of this bridge will change greatly about Ms. myuki in a single phrase.

WARR線3つめの橋が完成しました。
Gunda地域にあるGunda駅の東隣にはSandgrass Roadがあります。この公道を越えるための橋がSandgrass Overbridgeです。
この橋は非常に特徴のある形になりました。当初の計画では変哲のないトラス橋になる予定でしたが、myukiさんの一言でこの橋の運命は大きく変わることに。


She said so.
"Let's hang it."

彼女はこう言いました。
『吊りましょう』と。

There is only 31m length of the digit that crosses road.
It is only several meters longer than Sandhill Sage Overbridge. Therefore, it was thought that this bridge was enough by a simple truss bridge.

道路を渡る桁は31mしかありません。
Sandhill Sage Overbridgeよりも数m長くなっています。このため当初は通常のトラス橋が作られる計画でした。

When the photograph is seen, it has the mysterious shape that cannot be indescribably said.
It is shape to mix the arch bridge with the cable-stayed bridge. However, is such a bridge in the real world?

写真を見ていただくと、なんとも言えない不思議な形をしています。
アーチ橋と斜張橋をミックスした形になっていますが、現実世界でこのような橋はあるのでしょうか?


A mysterious point in this bridge is not only shape.
A big arch diagonally steps over the railway track and exceeds it.
Therefore, it looks very unstable. If the railway track was a double-track line, such instability might not have been born.

この橋の不思議なところは形だけではありません。
大きなアーチは、実は線路を斜めに跨ぎ越しています。
線路が複線なら、このような不安定に見えることをする必要はなかったでしょう。


There was an idea to intersect two arches, too. However, I decided to adjust the arch to one because I had looked very exaggerated it.
Because the bridge girder is hung, the space under that is very widespread.

アーチを2つ交差させる案もありました。でもそうすると大げさに見えてしまったので、結局アーチは一つになりました。
橋桁を懸架したため、その下の空間はとても広々としています。

WARR Tech :: The best height of overhead wiring in Inworld Electric Railways

I thought that I was going to give the trait that did not exist in other railways in the WARR line. I decided to construct the WARR line as Electric Railways because there was fortunately room in the number of Prim of land in the WARR line.

However, railways of the Second Life did not have Electric Railways up to now. The exception is UR Rail System. However, this is the one of a standard different from SLRR.

There is no regulations of Electric Railways in the standard of SLRR yet. The importance is height of the overhead wiring. As a result, the size of the railway vehicle that can go into the railway track is decided.

Then, I looked for the tallest vehicle in Second Life.

It was M's R&D that I went first. I decided to turn from the vicinity quickly.

The maximum locomotive in M's is Garaxy. The about 5.8m height existed.

Next, it was H8 Motors that I went. Various locomotives have been exhibited here. Their steam locomotive was short, and about 5m all. However, the diesel locomotive of an American style was very large, and had height of 6.5m.
I am not because I saw all the railway vehicles. However, another had only one railway vehicle equaling this locomotive tall.

If the height of the overhead wiring is made higher, it is likely to be made any vehicle run the railway track. However, the construction of the railway track becomes more difficult. The problem is made confusing as for there is a limit in the change in the altitude of land in Second Life.

In the real world, 6m a lot is seen in a European region. Moreover, it is 7m or more in United States, and about 5m in Japan.

Because the standard doesn't exist, and electrification also has the opinion of unnecessary to begin with, the change of the WARR line to Electric Railways already seems to have twist and turn for a while.

WARR Today :: Andraca Station

The construction of the Andraca station started.

Andraca駅の建設が始まりました。

This station is a terminal of the first stage construction.
There is a switch in the east of the station, and is one platform and are two railway tracks at the station.
The railway track that diverges with the switch and is postponed to the northwest might be connected with the second stage.
This switch is considerably an acute angle assuming that it is in the main line, and the train that passes over here will have to go slowly.

この駅が第一期工事の終点になります。
駅の東方にポイントがあり、1面2線の構成です。
Gunda方面から入ってきて右に延びる線が将来の第二期へとつながる線になります。
このポイントは本線の分岐としてはかなり急角度です。


The overhead wiring pillar is seen to be built at the station.
I decided to provide a structural standard concerning the overhead wiring, and to reproduce the electrification railway in the WARR line.

これまでのWARR線では見られなかった架線柱が見えます。
架線とそれに付帯する構造の規格を定めて、WARR線は最終的に電化鉄道線を再現することにしました。

There is 6m height from the top of the rail under the overhead wiring.
I decided this height referring to the height of the body of the Garaxy steam locomotive made of MsR&D.
I also investigated the height of vehicles made by H8 Motors.
It is thought that the vehicle where height more than this is needed is very few though it is not because all railway vehicles of InWorld were confirmed.

レール面上から架線までの高さは6mあります。
この高さはM's R&D製のGaraxy蒸気機関車の車体高さを参考にして決定しました。
InWorldの全鉄道車両で確認したわけではありませんが、これ以上を必要とする車両もそうそうないだろうということで。


There is Andraca Overbridge that is the maximum bridge in the WARR line next to the station.
This is Suspension Bridge with just 50m span between towers.
The switch in the station east is set up on this bridge.
This shows narrowness on the site.

駅の隣にはWARR線最大の橋であるAndraca Overbridgeがあります。
これはタワー間のスパンがちょうど50mある吊り橋です。
駅手前のポイントは、この吊り橋上に設置されています。
こんなところにも敷地の狭さが見え隠れしています。


This photograph is from a station platform to the appearance in the east.
Do you see the switch is on the bridge?
This Suspension Bridge is a kind of single span bridge, and the structure that only the digit between towers is hung with the cable. Both of the digit outside of the tower are away from the cable. Therefore, the switch can be set up on the bridge.
To set up the switch here, this bridge became a single span bridge.

駅ホームから東を望みます。
ポイントの位置は既に吊り橋の上なのが分かるでしょうか。
この吊り橋は単径間橋で、桁がケーブルで支えられているのはタワーの間の1スパンのみという構造です。タワーの外側は通常のトラス構造になっているので、左右非対称なポイントの設置ができます。
むしろポイントを設置するために単径間構造になったと言うべきですが。

WARR Today :: Plan was changed.

Please look at WARR development webpage also.


The plan of the WARR line was changed dated June 1.
As a result, construction will be discontinued in a part of section.

6月1日付でWARR線のルート計画を変更しました。
これにより一部の区間で建設済み線路の廃止と建設の中止が生じることになります。

The section from Andraca to Achlya is concretely abolished and the section from PruniJunction to Eson is discontinued.
The Andraca station is shifted position and will be constructed.

具体的にはAndracaからAchlyaまでの区間を廃止とし、Pruni JunctionからEson周辺に至る区間を計画中止とします。
Andraca駅は位置を変えて建設することになります。


The position of the Andraca station will become the south from a current plan. Therefore, the starting station and each schedule station of the second stage will be changed.
In the terminal position of the second stage, there is no change. The site of a last point has already been acquired.

Andraca駅の位置はこれまでの計画よりも南になり、これに伴って予定されていた第2期建設の開始位置も変更になります。さらに第2期の予定駅も変更になります。
第2期の終点位置は変更ありません。既に終着点の用地は取得済みです。

To evade the site acquisition of the addition, I restructured the arrangement of the railway track in the Lida station west .

Lida駅西方の配線を見直し、追加の用地取得を回避するように再構築しました。


In a current plan, the railway track that had gone out of the Lida station was extended to the Rosieri region in the straight line as it was. However, this plan needed a further additional site. Because the division of this district was very complex, the whole line opening to traffic in the WARR line might be very delayed in a plan as it is. Then, the railway track arrangement is reexamined, I succeeded in constructing the route that came off to the Gunda region stealing the site that had been acquired while drawing the S-curve.

これまでの計画ではLida駅を出た線路はそのまま直線的に延びて北隣のRosieri地域へ進入する予定でした。しかしこれはさらなる追加用地が必要でした。この地区の区割りは非常に複雑でしたので、計画にこだわるとWARR線の全線開通が非常に遅れるおそれがありました。そこで線形の見直しを行い、S字カーブを描きながら取得済みの用地をかすめつつGunda地域へと抜けるルートの構築に成功しました。

The site not started constructing between Lida and Gunda became another division. The opening to traffic of this section has advanced one step.

これでLida-Gunda間に必要な用地は残り一区画となり、この区間の早期開通に一つのめどが立ったものと考えられます。
