@railroute-ts/cis

Former-USSR mainline rail (Russia, Kazakhstan, Belarus, Ukraine, Caucasus, Central Asia; 1520 mm) from OpenStreetMap — the land bridge between @railroute-ts/china and @railroute-ts/europe. Stations by English name.

npm install railroute-ts @railroute-ts/cis @railroute-ts/china @railroute-ts/europe

Eurasia land bridge — China → Europe by rail

import { railRoute, mergeNetworks, registerStations } from 'railroute-ts';
import { CHINA_NETWORK, CHINA_STATIONS } from '@railroute-ts/china';
import { CIS_NETWORK, CIS_STATIONS } from '@railroute-ts/cis';
import { EUROPE_NETWORK, EUROPE_STATIONS } from '@railroute-ts/europe';

const EURASIA = mergeNetworks([CHINA_NETWORK, CIS_NETWORK, EUROPE_NETWORK]);   // once, ~2 s
registerStations([...CHINA_STATIONS, ...CIS_STATIONS, ...EUROPE_STATIONS]);

const r = railRoute('Chongqing', 'Duisburg Hauptbahnhof', { network: EURASIA, gaugeChangePenaltyKm: 300 });
r.properties.length;        // ≈ 11,000 km
r.properties.gaugeChanges;  // 2 — 1435 → 1520 at Dostyk/Alashankou, 1520 → 1435 at Brest/Małaszewicze

The three packages are built from the same OSM data with non-overlapping boxes, so they share node coordinates at the borders; mergeNetworks bridges any remaining dead ends within 2 km. Trans-Siberian, Trans-Mongolian (via the china package, which already contains Mongolia), Baikal–Amur and the Central Asian corridors are included; Sakhalin and Far-East ferries where OSM tags them.
