I was doing a bit of research (as always) and this time into headlamp codes and discovered this useful site:-

GWR Headlamp Codes

Its hard to beat a GWR express train accelerating out of Paddington heading for Penzance with full on headlamps shouting "get out of my way, I'm quick!"

If anybody else discovers useful info about lights and discs as they should be applied to the front of locomotives then please add to this topic. Lets keep the info on this together.

Happy modelling

Here is the British Rail codes information.

British Railways Standard Headlamp Codes

Four positions are used for headlamp, one on the smokebox below the funnel, and three on the buffer beam, one in the middle, and the other two approximately one over each of the buffers.

Diagramtically, they are shown thus, looking towards the train, with O for a lamp, and x an empty bracket:

O
OxO (This combination of three lamps reserved for a royal train)

The codes:

x
OxO
Group 1: Express Passenger Train. Breakdown Train going to clear the line, o Light Engine going to assist disabled train. Empty Coaching-Stock Train timed at express passenger train speed.

O
xxx
Group 2: Ordinary Passenger Train. Mixed Train. Breakdown Train not going to clear the line. Branch Passenger Train. Rail Motor Train or Railcar.

O
Oxx
Group 3: Express Freight or Ballast Train authorised to run at a maximum speed of 35 mph. Empty Coaching-Stock Train not carrying headlamps for group 1.

x
OOx
Group 4: Parcels, Nespaper, Fish, Meat, Fruit, Milk, Horsebox, Cattle or Perishable Goods Train composed of vacuum-braked stock with brake pipe connected to engine. Express Freight Train. Livestock, Perishable or Ballast Train with not less than one-third of the vacuum-braked vehicles connected to the engine.

O
xxO
Group 5: Freight Mineral or Ballast Train. Train of empties carrying a through load to destination.(?)

O
xOx
Group 6: Express Freight, Fish, Meat, Fruit or Cattle Train. Ballast Train not running under group 3 or 4 headlamps. Special Train conveying 36 ton breakdown crane but not proceeding to an accident.

x
xOx
Group 7: Through Fast Train not running under group 3, 4 or 5 headlamps and carrying a through load.

x
xOO
Group 8: Light Engine or Light Engines coupled together. Engine and brakevan.

x
Oxx
Group 9: Freight, Mineral or Ballast Train stopping at intermediate stations.

x
xxO
Group 10: Ballast, Freight or Inspection Train requiring to stop between signal boxes (in the section). Branch Freight Train.

N.B. Headlamp codes are subject to alteration in the case of "through" trains working over branch lines, and also to minor variations on the different Regions of British Railways.

Prior to the class 1-10 trains there were Class A to K; these were almost, but not quite the same as the classes 1-10. There were minor differences in the headcodes too. These following were taken from a copy of the 1960 'General Appendix to Working Timetables and books of Rules and Regulations' published by the Railway Clearing House on behalf of the General Managers of the various BR regions. (This, like other such publications, gives much useful detail on the operation of the prototype. Often available at Book and Railway Fairs, swapmeets and the like - mine cost me £2.)
Using the same style of code as Gary:

x
0x0 Class A - express passenger, newspaper, breakdown train or snow plough going to clear line, light loco going to assist disabled train, inspection train not stopping in section.

0
xxx Class B - Ordinary passenger or mixed train or breakdown train not going to clear line - Branch passenger train where authorised by regional Operating Officer.

x
00x Class C - Parcels/fish/fruit/horse/livestock/meat/milk/pigeon or other perishable train with stock conforming to passenger stock requirements. Above and ballast trains with at least half of train with automatic brake on at least half the vehicles. Empty coaching stock train not authorised to carry 'A' code.

0
0xx Class D - Express freight, perishable or ballast train with at least one third of vehicles fitted with operative automatic brake.

x
x00 - Class E - as D but with only 4 vehicles attached to engine with operative automatic brake or as D but with a limited load of vehicles none of which is fitted with the automatic brake.

0
xx0 - Class F - as D but with no vehicles fitted with automatic brake.

x
x0x - Class G - Light engine or engines coupled togther, light engine with brake van

0
x0x - Class H - Through freight or ballast train not running under Class C,D,E or F headcodes.

x
0xx - Class J - Mineral or empty wagon train

x
xx0 - Class K - Freight, mineral or ballast train stopping at intermediate stations, lbranch freight train where authorised, Freight, ballast or inspection train requiring to stop in section.

Now how do we get a minature train crew to change the headlamps when the class of a train changes at a station stop?
