1836Jr30

1. Setting, map and number of players
1830 covers the northeastern USA for 2-6 players. 1836Jr30 moves the action to the Netherlands and Belgium (Amsterdam, Rotterdam, Brussels, Antwerp, with off-board destinations toward Paris, Cologne, Hamburg and Strasbourg), designed for 2-4 players only. It's literally a "junior" game: it reuses physical components from 1830 (trains, the stock market, even some tile types) but with a map and numbers built for much shorter, simpler games.

2. Six operating companies instead of eight
1830 has eight operating companies. 1836Jr30 has only six: the Chemins de Fer de l'État Belge (B), the Grande Compagnie du Luxembourg (GCL), the Chemin de Fer du Nord, the NBDS, the HSM, and the NFL. The number of privates, however, stays the same: six, just like in 1830.

3. Bank and treasuries cut in half
1830's bank holds $12,000. 1836Jr30's holds only $6,000, exactly half. Starting cash per player and certificate limits are also scaled down proportionally (for example, the certificate limit at 4 players drops from 16 in 1830 to 10 in 1836Jr30), reflecting a smaller economy for a shorter game.

4. A private with a "teleport" power
The Charbonnages du Hainaut lets its owning company lay a tile and a station token on hex J8 for just the mountain terrain cost, without needing the track to connect to any existing tile of that company (or any company at all). None of 1830's six privates ever allows such a disconnected placement.

5. The Enkhuizen-Stavoren Ferry, over the old Zuiderzee
The Enkhuizen-Stavoren Ferry private lets its owning company lay a free tile on hex B8 — the IJsselmeer water crossing, the historic Zuiderzee — in addition to its normal tile lay for the turn. It's a very local geographic bonus with no equivalent in 1830.

6. Two privates that convert directly into shares
The Grand Central Belge can be exchanged for a 10% certificate of company B (from the bank or the pool), closing the private when it happens. The Chemins de Fer Luxembourgeois comes bundled, from the moment it's bought, with a 10% certificate of the GCL. None of 1830's six privates behaves this way.

7. A "B&O-style" private
The Chemin de Fer de Lille à Valenciennes comes bundled with the President's Certificate of the Chemin de Fer du Nord (forcing its par price to be set immediately), can never be sold to a corporation, and closes when the Nord buys its first train. It's exactly the same concept as 1830's B&O.

8. Train prices and rust rules identical to 1830, but with limited Diesels
The price and rust schedule for every train type (2/3/4/5/6/Diesel) are exactly the same as in 1830: $80/$180/$300/$450/$630/$1,100, with the same $300 trade-in discount per old train when buying a Diesel. The difference is that 1830 has unlimited Diesels, while 1836Jr30 has only 5 copies.

9. 1830's own tiles, relocated onto the new map
Amsterdam uses the same special "NY" tile type that 1830 reserves for New York; Rotterdam, Arnhem-Nijmegen and Maastricht-Liège use double-city "OO" tiles; Brussels and Lille use "B"-type tiles. These are the very same tile categories from 1830's set, simply relocated onto Dutch and Belgian cities.

10. Ports that add a bonus instead of paying their own revenue
Harwich, Dover and Paris don't work like 1830's off-board destinations (which pay their own value when a route ends there): a route can never end at these ports, but if it passes through one — as long as it includes at least two other real stops — it adds a flat bonus (+20 in the green phase, +30 in brown). In 1830 off-board destinations simply pay their own value just like any other city.

1836Jr30 — Schematic summary (vs 1830)

SETTING

• The Netherlands and Belgium, with off-board destinations toward Paris, Cologne, Hamburg and Strasbourg
• 2-4 players (vs 2-6 in 1830); reuses physical components from 1830 (trains, market, some tiles)

COMPANIES AND ECONOMY

• 6 operating companies (vs 8 in 1830); 6 privates (same as 1830)
• $6,000 bank (half of 1830's $12,000); starting cash and certificate limits reduced proportionally

NOTABLE PRIVATES

• Charbonnages du Hainaut: "teleport" tile-and-token placement, with no connection to the existing network
• Enkhuizen-Stavoren Ferry: free tile at the old Zuiderzee water crossing (hex B8)
• Grand Central Belge and Chemins de Fer Luxembourgeois: convert into 10% certificates of a company
• Chemin de Fer de Lille à Valenciennes: "B&O-style" private, tied to the Nord's president's certificate

TRAINS AND TILES

• Same prices and rust schedule as 1830 ($80/180/300/450/630/1,100), but only 5 Diesels (not unlimited)
• Reuses 1830 tile types (NY at Amsterdam, OO at several cities, B at Brussels and Lille)

PORTS AND BONUSES

• Harwich, Dover and Paris pay no revenue of their own: they add +20 (green) or +30 (brown) to a route that already includes at least two other stops
• In 1830, off-board destinations always pay their own value like any other city
