Quick check confirms tender leading consist now shows fuel/water in the HUD.

For articulated you will have to use 0 for tender required and use half of tender coal and water values for weight for first part of loco and 1 for second half .Do you then use what values for the tender ? Just half of the actual load of the tender ? Example - Virginian ?
When this is done you don't get the no coal, no water notice but won't the extra weight on the front half affect the traction etc.

Nice problem to solve, one I saw coming a long time ago. It is time for two things to happen, first, some way of consolidating the two eng files so they are considered as one power unit, and second the expansion of the numbers of bogies and wheels that can be used in a single model for new OR only items.

What I've done so far is - add the half weights of coal and water to the front parts mass , then taken the same percentage of weight on Drives that the original had from the new increased mass . Works better to control front half wheelslip . Doesn't change loco total mass + tender loaded mass . Both halves now have equal coal and water - front is on board like a tank engine and back half gets it's fuel from the other half of the total that remains in the tender .
I know it's a work around but give me some better suggestions and I'll try them .

Hi, Can we also have

IsTenderRequired(0)_ The locomotive is a tank locomotive.

IsTenderRequired(1)_ Main engine fuel tender. (Water & Coal)

IsTenderRequired(2)_Main engine tender and 1 aux water tender in the consist.

IsTenderRequired(3)_Main engine tender and 2 aux water tenders in the consist.


By far the most encountered scenerio is the use of extra tenders for water. But, On oil burning steam locomotives the use of a second tender could also hold both fuel and water. Take Canadian Pacific Royal Hudson 2860 for example My link Notice the wisp of steam from the second locomotive tender. The steam heats the heavy oil the locomotive burns so it can be pumped from tender to tender.

Maybe in the future the weights and volumes can be placed in the wag files and actually reduce as water/fuel is used.

Also locomotives like the gas turbines had their fuel in seperate tenders. Yet, MSTS does not have the option for tender operation in say diesel mode. Some diesels like those on the trans Australia Railway use diesel fuel tenders because of the vast distances traversed. We also have LNG being tested on diesels in the US and Canada.

ORTS does not actually read the tender fuel or water levels and therefore correct tender perimeters cannot be setup in ORTS. As the tender fuel is depeleted the weight of the tender and it's pyhsics also change. The steam locomotive also changes as the weight of the tender and load on the locomotive changes.

The pyshics of ORTS would need to be adjusted to account for the mass of the tender and the varying amount of water coal or oil that is on board the tender.

Then we could have say up to a total number of tenders being 4. This would allow for ORTS to use water tenders and register the extra water capacity.

For variable weight in tender and locomotive please read http://www.elvastowe...sics-variation/

Interesting, I hope something comes of further improvements.

So what about having two water tenders which is what I am really after at the end of the day?

In the USA we have two water tenders on the Union Pacific steam excursions since the big locos require so much water. In the past this would have been the Challenger and soon will be the case with Big Boy 4014.

Already implemented. Section 8.4.5 of the current manual explains how.

That being two auxiliary water tenders aside from the main loco tender?

Only one way to find out. Set up two extra tenders with the parameter added to each wag file and see what you get.
