chengdu_chongqing railway v0.6成渝铁路

上传系统似乎出了问题，地图文件仍然是前几天的旧版本。所以我刚才重新上传了文件，自己试了一下，现在看起来没问题了。 

There seemed to be a problem with the upload system; the map file was still an older version from a few days ago. So I just re-uploaded the file and tested it myself, and it seems to be working fine now. 

更新记录： 0.1增加了成都和重庆周边的卫星城市，降低了区域辐射和污染重复。这样可以把机场火车站都放到了隔壁市。

0.2 重放了成都。

0.5完全重建了整个地表贴图和高山河流的局贴图。实现了基本都江的贴图。岷江支流，当然只是贴图。显然通航的还是只有四大江。因为这个游戏只有平面水，完全不可能高低差。

0.6稍微改变了下成都的需求，增加了一些产业。 

【背景】 1949年底解放。1950年6月15日，成渝铁路开工——新中国自己修的条铁路，四川人盼了四十年的那条线。 1952年7月1日全线通车，505公里，用国产钢轨、国产水泥、沿线人力挖掘肩挑修出来的。 这张图就是最北路的阶段。 【地图】 ·112×112瓦片= 28.67 km × 28.67 km（巨型） · 领土 160 m（盆底）～2500 m（西缘山地），龙泉山、华蓥山把盆地切开 · 53座城镇，规模尺寸 0.38～2.57：成都、州、宜宾、泸、南充、乐山、德阳、达州…… · 59座产业、23类，全部按各地现实特产落点（上市见README） · 图上1公里 ≈ 现实10公里（约1:10压缩） 【主线：成渝铁路，10站】 成都 → 简阳 → 资阳 → 资中 → 内江 → 隆昌 → 荣昌 → 永川 → 江津 → 图上约27公里，按1:10折算 ≈ 现实375公里（现实成渝线 505 公里） ·一期成都—资阳：盆栽几乎零坡度，成本最低，先把钱爬起来 ·二期资中—隆昌：必须重庆跨沱江，全线唯一的硬工程——桥位可能是灵魂·三期底荣昌—：进 平行岭，路堤短隧道交替，钱烧得最快，前两期利润就是为积累的 建议1950年开局：先用河道运船跑通渝间的高价值货，攒够再动土。 【副线：四条江上的供应链】 主线确定，四条大江各自成链，既是第一桶金，也独立于铁路的玩法。 · 长江重庆·川江段（宜宾→泸州→合江→江津→）：最宜肥的一条。宜宾、泸州酒厂的白酒南下重庆，泸州附近有化肥、液压件、砂石； 回程带重庆岷江（成都→眉山→ 乐山→宜宾）：夹江陶瓷、石英玻璃、眉山泡菜、家具等各类建材重货， 走水运最划算，宾中转进长江。· 沱江（金堂→简阳→资阳→资中→内江→泸州）：血橙柠檬类生鲜、羊肉、甜城蜜饯；生鲜有时效， 先船后铁，泸州汇入长江后入川江大链。 嘉陵江（阆中→南充→武胜→合川→重庆）：「丝绸都」三件套丝绸→织造→重庆成衣， 外加保宁酒、牛肉制品，全程水运直达

Background:  Sichuan was liberated at the end of 1949. On June 15, 1950, construction began on the Chengdu-Chongqing Railway—a newly established railway in China with independent capabilities, a railway Sichuan had longed for for forty years. The railway opened to traffic on July 1, 1952: 505 kilometers long, entirely constructed using domestically produced cement, and entirely by hand. This phase is depicted on the map. Map - 112 x 112 grids = 28.67 km x 28.67 km (Giant) - Bay range: 160 m (basin bottom) to 2500 m (western mountains); the Longquan Ridge and Huaying Ridge divide the basin into several independent areas —53 towns, with area ratios ranging from 0.38 to 2.57: Chengdu, Chongqing, Yibin, Luzhou, Nanchong, Leshan, Deyang, Dazhou, etc. —59 industries of 23 types, each originating from local specialties—Scale: 1 km on the map is approximately equal to 10 km in reality ( approximately 1:10). Chengdu to Chongqing Railway, with 10 stations: Chengdu —Jianyang—Ziyang—Zizhong—Neijiang—Longchang—Rongchang—Yongchuan— Jiangjin—Chongqing. Approximately 27 km on the map, approximately 375 km at a 1:10 scale—consistent with the actual 505 km line shape. —Phase 1: Chengdu—Ziyang: Basin bridges, almost no gradient, lowest-cost rail. —Phase 2: Zizhong—Longchang: Requires crossing the Tuojiang River. The only real engineering problem on the entire line; bridge positioning is the soul of this line. —Phase 3: Rongchang to Phase 3: A winding route through ridges and valleys, entirely embankments and short tunnels . This is where the money was lost—Phase 1 and 2 were used to pay for some of the costs. Around 1950: High-value goods were transported along the river first, then construction began. This branch line: Four major freight logistics chains each had their own freight chain. These were the paths where you spent your first pot of gold, and these freight chains remained profitable for a period after the railway opened. —Yangtze River, Chongqing section (Yibin—Luzhou—Hejiang—Jiangjin—): The richest city, Chongqing. Baijiu from Yibin and Luzhou distilleries was transported downstream; Luzhou also exported fertilizers, water conservancy machinery, and sand; this equipment and machinery was transported upstream back to Chongqing. - Minjiang River (Chengdu—Meishan—Leshan—Yibin): Jiajiang ceramics, quartz glass, pickled vegetables, furniture—old-style building materials are transported by water at the lowest cost, then transshipped to the Yangtze River in Yibin. - Tuojiang River (Jintang—Jianyang—Ziyang—Zizhong)—Neijiang—Luzhou: Blood oranges, lemons, mutton, candied fruit. Perishable goods are first transported by ship, then by rail; Luzhou and Chongqing transport all goods to the Yangtze River via pipeline. - Jialing River (Longzhong—Nanchong—Wusheng—Hechuan): The same river chain, "Silk City" series products—silkworm/cotton, textiles, clothing—plus vinegar and pickled beef, extend all the way to Chongqing.
