1915: Futuristic (+5): Unrestricted calibre railway guns

Motorization

1900:  Experimental:  A few cars and trucks have been bought by your army to see what they can do; everything else follows from this.  This tech is granted automatically once the nation has the following techs researched:  1900 Internal Combustion Engines and either 1895 Line Infantry or Light/Cavalry

1910:  Motorized HQ, Artillery units; improved tactical mobility  
1920:  All supporting elements motorized; improved strategic mobility
1930:  Troops mounted; improved tactical firepower/mobility, strategic mobility.

Light Armor

1905:  Historical 1907 civilian vehicles (unreliable) with improvised armor and machine gun mount.  Prerequisite:   1900 Motorization.  
1910:  Historical 1912 armored cars
1915:  Historical 1917 tankettes (unreliable) and armored cars
1920:  Historical 1922 tankettes and armored cars

Heavy Armour

1910:  Historical 1916 tanks (very unreliable).  Pre-requisite  :    1900 Motorization.
1915:  Historical 1917 tanks (unreliable)
1920:  historical 1922 tanks

Signals/Intelligence

Note:  Had been a "secret" tech for a while.

1895:  Ability to create simple codes (if a player requests this ability.)
1900:  Ability to use and break simple codes, bored crews at wireless stations listening to radio traffic
1905:  Basic encoding protocols, dedicated radio and telegraph line listening stations
1912:  Centralized cryptographic institutions, enforced radio discipline, Room 40
1920:  Primitive mechanical encoding/decoding machines etc.

Rocketry
1910:  Black powder rockets .Comparable to light field guns in effect  but utterly unreliable and inaccurate.
1920:  The start of new rocket theories, experiments with vastly different propellants, active mechanical flight stabilization.
1926:  Experiments with liquid fueled rockets. Dependable solid fuel rocket weapon systems on light field gun level.
1935:  Solid fueled siege rockets, liquid fuel rocket weapon ystems in experimental phase.
1942:  Solid fueled area effect missile systems (Katyusha), less reliable long range liquid fuel rockets available (early A4) in small quantities.

Edits:

Edit: Re-worded the 1910 Reserves tech to conform with the mobilization rule.

Deleted and replaced by MTB Tech as of 1/16:

Internal Combustion Engines (Land, submarines, and air)
Dated (-1): none
1895 Baseline (0): Gas, petrol(gasoline) and alcohol-fueled engines up to 20HP
1900 Advanced (+1): Land and airship engines up to 200HP, 50HP aeroplane engines

Additions for 1/1918 (done on Oct 29, 2009):

• Extended Infantry progression
• Extended Light Infantry progression
• Extended heavier than air aircraft progression
• Added Rocketry Tech Progression
• Replaced Anti-Aircraft Gun tech, which was:

1900:  Baseline (0): High angle anti-ballon guns or machine guns (up to 1 pounders) = 1,000 feet - starting point for everyone.
High-angle anti-balloon guns are perfect for that role.
1908:  Advanced (+1): High angle anti-air guns (20-40mm) = 5,000 feet
1914:  Cutting Edge (+3): High angle artillery (40-80mm) = 15,000 feet
1925:  Futuristic (+5): High altitude artillery (80mm+) = 30,000 feet
