Talyllyn engines havn't enough water

RobertM · Post by **RobertM** » Mon May 09, 2005 2:59 pm

To all,

I was just wondering if the engines on the Talyllyn V2 have accurate water tank capacity?
I was jsut wondering because I have just created an activity where you have too run all the way from Tywyn Wharf too Nant Gwernol and then back down to Tywyn Wharf, but on the return journey there is hardly any water in the water tanks as leave Nat Gwernol.
The question that I'm asking is, are the tanks accurate or do the physics use more water more quickly than the real Talyllyn engines?

MSTS engine physics have always been a bit odd on Narrow Gauge stuff, Steve, is Aber water tank there? If so you could refil there, if its been included in the route. If not, try and make it to Dolgoch. Assume the activity refils the tanks at Dolgoch on the up train?

Yes it is authentic. There is enough water to get you to Dolgoch Falls on the uphill run where you then take on water like the real Talylyllyn railway locos do, then there should be enough water to get you up the rest of the line and back down again.

There is no water colum at Aber and if I take on water at Dolgogh falls, I still don't have enough water. I only have enough to get too Nant Gwernol and then just beyond Aber on the return trip.

Improve your firing/driving them

On that note - do you leave the train brake in the "released" position? - When operating it should be in the "running" position to save steam.

Yep I had approx 190 gallons left in until Dolgoch, took on water to full capapcity and then used very little to get up to Nant Gwernol and next to none on the way back down, it requires modest use of the regulator, brakes and injectors.

Don't be cheaky, I'll have you know that I'm a trainee fireman at the Lakeside & Haverthwaite Railway!

And yes, I have the brake set in the 'Running' position.

Good for you, we all have too start somwhere though so don't show off!

AND I'LL HAVE YOU KNOW I'M NOT EVEN A TRAINEE TWIT, LET ALONE FIREMAN! NOW STOP ARGUING AND START DRIVING!

A helpful hint, when you fill up the tanks at Dolgoch on the uphill run, make sure the boiler is also completely full, (about 1.20, as it all sits at the back end) then top up the tanks again. That's what i did, being generous on the regulator as well and it worked out fine for me.

Its what we do with the panniers at SVR first thing in the morning so they can get to Bewdley light engine and bring a train back without taking on water.

If its really authentic, you should be able to get back to Twyn from just below dolgoch with the water left in the boiler... and none in the tanks

.....

not that that's ever happened of course

On a similar note to the rest of this thread, im a Talyllyn Cleaner

, and also run a steam roller.... its common practice on the road engines to do what David said and fill the boiler right up when you take on water, and then fill the tanks, to give you maximum water, you never know on the roads when you'll get some next!

Ok - I'll be honest - the water capacities and just about everything else in the ENG files for the TR locos are NOT authentic as to do so will make the locos un-runnable in MSTS

I found that the real NG values in MSTS were not suitable so I essentially "adjusted" the values to give me a result that felt about right in terms of power, water consumption etc. I found that the Tywyn to Dolgoch run was about right in giving the need to re-fill at Dolgoch or the loco would "blow-up". I admit I didn't test to see if I could get back to Tywyn but you should do considering hardly any steam is used on the down run.

BTW - the water tank at Aber doesn't exist in my version (I wasn't aware that there was one until too late in the build) but the Dolgoch, Pendre and Tywyn ones all work.

I have failed on a down run at Pendre for lack of steam, though, so the firing values need further adjusting !!

Unfortunately, its all guess work at this stage and if anyone can improve on the defaults to get more accuracy then let me know and I'll adjust the master copies.
Still - it's all part of the fun.......remember Dolgoch running out of water in Tom Rolts Railway Adventure ??

Wonder how many passengers did think the loco was about to blow up when they saw the crew running up the hill.
