A diagram details the work a loco/unit or crew member will be doing that day. A headcode identifies the train by type (class 1 express, class 0 light loco etc), where it is going and that particular service. For example 1V67 is an express passenger train heading for the Western region with 67 identifying that train. Apart from a few traction diagrams you generally won't find them online.

A headcode is the train reporting number or train description of a train. For example 4M21....the first digit represents the class of train, in this case a class 4 freight train. The second is the location identifier, in the case the M meaning destined for the midland zone and the last two digits are random or progressive to distinguish from other trains.

www.traintimes.im lists planned headcodes (sorry, reporting numbers) for passenger trains and also some ECS moves. Won't get freight and such and doesn't list realtime running information

Diagrams are very rarely given out for most TOCs, and I've been told more than once this is due to commercial confidentiality. However, on TOCs like East Coast is is easy enough to see what type of stock will be used.

Some gen groups have them, although they can be unreliable.

Bit out of the way for the OP but I have seen parts of diagrams at Manchester Piccadilly on the Northern platforms which details joins/splits of units and where they come from/go to. I have had a bit of a peek at them before though I don't like hanging around there for too long in case any of the staff take exception to it!

Open Train Times lists all passenger, charter, freight, ECS, engineering and light loco movements, and will show you what passes through a station, not just calls at it.

Just for clarity, the headcodes most commonly encountered are not in their full form.

The reason is this:

There are 6 trains today with 1A04 as their headcode. 2 of which both do Glasgow to Kilmarnock at different times.

The actual headcode may be 1A0432 etc.

:D

For example 1V67 is an express passenger train heading for the Western region with 67 identifying that train.

More specifically the letter indicates the route. On class 1 routes, some letters are reserved for trains going between two or more regions as follows: S = Scotland, M = LNW or Midland, E = LNE, L = Anglia, O = Kent/Sussex/Wessex and V = Western. Although sometimes class 1 trains bear these letters when they're not interregional. Other letters just refer to a particular route or destination within a region.

Class 2 trains (stoppers and other local services; class 2 means "low signalling priority") do not use region letters if they happen to cross between regions.

In those cases the unique identifiers are G60022 and G60023 (UIDs consist of a letter and five numbers, can't remember how they work).

There are only 4,600 possible passenger headcodes (two classes, 23 route letters* and 100 numbers), whereas there are far more than that number of trains each day.

Not all the way through though I assume!

1116 Cardiff Central - Holyhead 1615
1638 Holyhead - Cardiff Central 2119

Changing over at Chester?

Nope, worked the whole thing, Newport to Newport. I'm a steward, not a guard. All 9 hours 25 minutes of it. Doing it again on Monday. :)

They do sometimes, likewise some Class 1 trains don't use the region letters despite crossing between regions.
e.g FGW's services to Weymouth are 2Oxx as they are going to the Southern region, likewise Weymouth-Bristol trains are 2Vxx, heading to the Western region. FGW's Cardiff-Portsmouth and return trains are all 1Fxx headcodes, when they should be 1Vxx when heading to Cardiff and 1Oxx when heading to Portsmouth.
