Hi 
Are splitter and range changers being made compulsory.
I dont understand them 2 be honest

No, why would they be?
I think Iāve read somewhere that in not so distant future EU regs would require ātraining truckā to have at least eight forward gears but practically it makes only range change compulsory on those trucks.
Yes, vehicles first used after 1/10/03 require at least 8 forward gears for the UK C/CE test.
I see now, it was in relation to the test as opposed to a general rule.

An easy mistake Neil, when you read the original question.
Welcome to Trucknet, Edward, for what its worth I think all training vehicles should have range and split boxes.
or better still, Eaton twins

Except that the DSA are now waking up to the fact that the Truck industry, with modern engines, no longer fits anything other than a 6 speed to an 18 tonner, except for a small few specified for drawbar use.
Which means that whilst the industry wants new drivers to be trained in up to date vehicles, the only vehicles acceptable to the DSA will be older vehicles. The rule changes were drawn up some years and have not kept pace with engineering improvements.
Iāve even driven a 6 speed artic. I didnāt look to see what it was plated at. Obviously not 44tonnes, but they are about.

I guess the number of gears also relates to the power curve of the engine.
I mean the 7.5t Iveco (dont laugh) i had this week, on one particular hill it was screaming itās nuts off in 3rd, but chugging and not far off a stall in 4th. I guess if you had a bigger engine you could space the ratios out more like this, but smaller engines need closer gears. So if you were a manufacturer and came up with a very torquey engine you could get away with a 6 speed artic?
This is where a splitter comes in, it lets you have another gear between gears, so in my case if iād had a 3 1/2 it would have been perfect.
Esentially a splitter and a range changer are the same thing technically speaking. They allow you to have a H pattern gearshift with 2 or 4 different ranges giving you up 16 gears. As on a truck you wont always need to use āeveryā gear as you would in most cars, you only need to use half the gears most of the time, so the splitter gears arent used as much.
The Actros we have with the Teligent box, has 16 gears with no splitter or range change, but being an electronic shift you can jump several gears at once.

They are so you donāt need a 10foot long arm to reach the bottom gears 
.
The wagon I drive has got 16 forward gears and 4 reverse.
Its got a range change and a splitter. Without them the cab would have to be a lot wider, to allow for the travel on the gear stick.
Here is a link to the bit in our Driving FAQ section which explains Splitters and Range Changes.

One thing I didnāt see in link you posted is that itās also much easier to design and manufacture gearbox to withstand big amounts torque if number of gears is reasonably low. 16 gear gearbox with same durability than your current four gear gearbox would probably be connected directly to drive axle
Itās all change anyway - when I took my test you still had to double de-clutch, even though new boxes were syncromesh. Now, with new units Iām driving auto boxes are becoming far more common & Iāll bet you, in a few yearās time, manual boxes will have disappeared.
