37670 Brakes

rushdenx1 · Post by **rushdenx1** » Sun Dec 01, 2002 7:59 pm

I have just tried out the excellent 37670 hauling 8 Mk1 coaches. There seems to be a problem with the brakes. When they are applied the train does not slow down. Even on full the train hardly slows and I have to apply the emergency brake to actually stop it. Can someone tell me what the correct settings should be in the .wag file or how I can adjust them to make thm more responsive.
Thanks Kevin.

Are the coaches and loco's brakes the same?

I've had exactly the same problem with DRS 37259. Looks superb, (despite the DRS lights) but the brakes are pretty useless. Slid through Carlisle station with a nuclear flask train, then though it was possibly the combination of brake, so uncoupled from the train, but still had the same problem. The train brake is only really effective once the emergency brake is applied, although i found it could stop slightly better with the loco brake when 'light engine'.

This is a comment, i'm not sure wether its a critism or not , being unfirmiliar (sorry having a . day spelling, not sure wether things are right or not, doh!) with how it would perform in reality, but i'm pretty sure not like this, but when starting a diverted West Coast set from Settle, double headed with an EWS 37, 37259 started slipping, possibly the first diesel i've managed to do that with!

37670, the brakes are set to Vacuum, not air, try the readme to change it.
mine is set to air and works perfect.
this might be the case for 37259 as well.

Air brakes are the most effective of all,

it is possible to have a loco dual braked but i am not sure of the effect if you have a mixed rake of stock.

ALL wagons must have the same type or brakes as the loco for proper braking to work! - single pipe air and dual pipe air dont mix either.

I tired this out with a train recently......

Loco: Class 60 - 60037 - Air Braked - single pipe
Load: 3 100T tank waongs - Air Braked - single pipe

All stoped fine, braking normal

but add 10 TTA tanks with vacume brakes and i had a run away on my hands! Emergency brakes + 100% loco brakes + sand and full throttle reverse wouldnt stop the damn thing! When you add a wagon with deffering brakes you simply pass the load onto the few braked wagons, so i had 450 tons of TTA's leaning on the 60.

Switched the TTA,s to Single Pipe Air brakes and train stops normally!

Just goes to prove what a difference it makes!

Does anyone else think we should set a standard brake type for all modern locos and wagons from now on?

Modern Loco's and wagons: Air Braked single pipe
Steam Loco's and Vehicles: Vacuum braked
Others Dual Braked: Air single pipe and Vacuum

What do ya reccon lads?

This is something that's been asked before, but nothing ever came of it. I agree that some sort of standard would benifit all. At the end of the day it has to be a balance between acurate vehicles/brake types and how much time do you want to spend editing eng and wag files to get thinks to work.

It still doesnt solve the problem of the new DRS 37 being almost impossible to stop when light engine...........

There are a few things to watch out for when making up a consist. One is don't put a mk1 full brake behind the loco because if you do all the other coaches brakes become isolated and don't work meaning all you have to stop the train is the loco brake.

Also putting another locomotive behind the driving loco can sometimes isolate the coaches brakes.

Have you tried using the loco brake as opposed to the train brake when light engine? I found this problem with the class 40s. They stop a lot better with the loco brake ([&] keys) when LE.

Slightly better, but the brakes are still next to useless. Quicker to stick her in reverse or apply the emergency brake, though its hardly prototypical.

I downloaded both 37670 and 37259 to check them out. They appear to perform identically to Mark's other 37s in the brakes department. Running light engine, both stopped from 60mph in just 37 seconds with 70 psi in the brake cylinders. This equates to a deceleration of about 7%g (g being 9.81 m/s/s), which is fine. So I'm not sure what's happened to your ones.

The locomotive brake is used when running light engine, as there's obviously no need to use the train brake.

There is a problem with these locos when you have 'Vacuum_single_pipe' instead of air, which causes the loco brake cylinders to reach only 20-something psi with 100% train brake. I don't know if it's possible to fix it, as I haven't had the time to get my head round it yet

. I recommend changing it to 'Air_single_pipe' (see Mark's readme file), especially for 37670 and 37259 which are modern-day models.

ok try stopping a train with a non fitted freight, ie wagons with no brakes whatsoever

For some other daft reason my pc always decides to put spaces between every letter in the .eng file, and as a result i've never been able to successfully alter an .eng file on any loco.

crepello · Post by **crepello** » Wed Dec 04, 2002 12:37 pm

That's very odd. Are you using Wordpad to edit the files?

I could e-mail you the revised .eng file if you want.

Using wordpad, i think. Not on home pc o check at the moment. If not, how would i alter it?
