Hi everyone,

In a recent post (in 'Physics' concerning couplings) maxtedrw gave the following info - FR coaches = 4.7t and an empty skip (rugga) = 0.363t. Can we have more of this sort of accurate info please to help with the design of .eng files. A comprehensive list of tare weights for narrow gauge vehicles (FR and TR particularly) would be an excellent start.

The next would be any info on typical loadings ( I think the Ladies should take max. 9 and now so should the Alco - she was definitely max. 6 with the old boiler in my day!) and the section timings (if any modern driver can quote the passing times of, say, Gysgfa, Tank curve and Summit) as well as the station times. Thanks in anticipation.

Incidentally, Blanche took 10 unaided to Dduallt in 1973 with Derek Evans as driver and yours truly as fireman. She was on oil by then so no great physical effort on my part, only the mental stress! Instead of the usual 15mph we did a steady 10-11mph on the 1 in 80 and lost time all the way.

Aprrox weights for the TR engines:

1 = 14 tones
2 = 10 tones
3 = 7 tones
4 = 8 tones
6 = 5 1/2 tones
7 = 12 tones

Any more info give me a shout: christian@hartley-woolley.freeserve.co.uk

How could Talyllyn be heavier than Tom Rolt O_O Tom Rolt is...BIG!

This is what the TR website says:

1 = 12 tons
2 = 10 1/4 tons
3 = 9 1/4 tons
4 = 9 1/4 tons
6 = 8 tons
7 = 14 1/4 tons

That is in Imperial tons not Metric Tones I believe.

Thanks for that, guys.

I am really looking for info on coaches and wagons. I seem to be able to find details of most locos but accurate tare weights of the things they pull appear to be rocking horse manure.

Hi guys I have been lots of work trying to get a scale feel to x2 stock. Now just to be sure I have A) never driven a loco B) intend NO, NONE, Nothing critical of the chaps doing the design - its taken me weeks to make a wagon with the wheels goign round !!

What prompted me was some of the weights on the TR and WHLR sites which when I popped them in the eng files made them go very funny peculiar !!

The best I have is taken form all sorts of web sites and some photo scans (cos wagons have Tare marked on them) I also spent ages working out that 1 ton = 20 cwt =2240lbs ! cos wagons are marked in tons cwt lbs.

So. Hudson skips are 1 cubic yard capacity generally. I have never found any weights yet but I have a picyure of a horse pulling 3 and a man pushing 1 so I reckon full they are about 1 ton and empty perhaps 6.5cwt

Tallylyn wooden underframed waste wagons have a tare of 0 11 3 in my photo (ie 11cwt ?) Corris metal bodied (possibly close to TR wagons) are 2 tons gross. generally slate wagons seem to be 2 ton capacity but the FR later designs seem to weigh in at 3 ton.

Linton and Barstable stock (close to Soputhwold and a sort of standard wagon on a NG chasis) both open plank and box vans have a 4 ton gross and 2.7.3 (plank) and 2.11.3 (box) tare.

In my book on a railway in france which used Decauville stock boggie open stock is shown as TYpe A - 10 ton and Type B 6 ton stock and interestingly the closed boggie box cars are also 6 ton stock. Now the Linton and Barnstable also had boggie stock of 8 ton capacity with a tare of 5.5.2 !! Is this really 5 ton, 5cwt, 2 lbs ?? not much load in that !! and the L&B 4 ton open wagons had a Tare of 2.7.3

So what does this add upto ? I feel that I have got the beginnings of an idea of some rules for getting Tare weights for stock. At least it means I can now set the wagon to feel right empty and then add load and see what happens. Way suprising ! Couplings and heavy wagons pushing flat cars off the track - sigh.

Sounds like an interesting project, ive been tinkering with the eng files for some time now, so I hope you have more luck than me, if you require any info on talyllyn stock, or a BETA tester to try it all out, give me a bell....

Hi folks,

Thanks for the info maxtedrw. I have been 'en vacances' for 2 weeks so will now get down to see how your info works out.
Incidentally, I can't believe thet nobody out there knows the tare of an FR Barn - they're so new!

lost heart a bit. I can get right weights and then get frictions from the calculator but couplings are proving to be a real pain. I thought I had it cracked but then when coupling to a loose consist I ended up inside the wagon. grrrrr

I am almost at a loss for what to do. Using a front coupler Wagons in a consist work fine but try pick ups of loose wagons and the whole thing goes belly up. It is almost as if different rules apply to loose consists that mean that they don't know that they are the same as connected consists. What is really strange is dropping wagons of a connected consist and then picking them up works ok.

Part of me wants to pack it all in and go back to the as downloaded settings just to have game fun and part of me refuses to be beat by a ruddy computer.

I am still struggling to understand if there is any kind of relationship between wagon weight and coupling settings. It all seems pretty random. Compared to flightsim it is a real mares tail. hey ho !
