Trailing Loads for Engineers Trains

[trainmania100]

Hi,

I understand that trailing timing loads on RTT for trains aren't actually about the weight of the train.
But engineers trains often have different trailing loads

Does this actually refer to what the load is?
Some ballast trains show trailing load 800 tonnes whereas others show trailing load 1600 tonnes. Some say 400 some say 600.

Does this actually mean anything? They are all timed for 60mph max where it is class 6 so what does the weight refer to?
I was wondering if they refer to the actual load such as ballast or sleepers.
2400 is usually the mobc and 715 is tamper

Im sure there are plenty of threads already out there explaining that trailing load isnt the weight but im interested in finding out what the difference is between these different engineers schedules

Many thanks

There isn't a direct 1:1 correspondence, but it's a reasonable guess that 1600 tons is likely to be loaded ballast or rails and 400/600 is the empties going the other way.

In my travels out & about on the rail network the 715 tonnes is 99% of the time a track machine.

That seems reasonable, however most of the time with ballast, its full going both into and out of the possession, in with fresh ballast, out with the old ballast

Strangely enough, loaded stone trains into my local freight yard are marked as TL 1400 tonnes; and the empties going back are 1600 tonnes!

Thankyou, yes most of the time it is a track machine,
Some steam locomotive workings are also classed at 715

Freight should be timed based on trailing weight provided it is given. The 715 tonne trailing load (60-TR40) is the most populated in the system with running times so a lot of engineer (and other) trains tend to default to that. Class 4 tend to be 1235 tonnes, Class 6 at 2000 tonnes. These now get increased significantly for future enhancement modelling with Class 4 at 1800 tonnes and Class 6 at 2600 tonnes trailing.
