That's a good observation -- oil in actual barrels would have been a lot more mixable with other cargoes than modern dedicated liquid containers.  And the smaller ships (<100 units. like the new PS Industry) are too small to really capture a diverse set of cargo.  Given that argument, I could see Handysize and Clanline staying the way they are.

What about Windjammer, though?  Is 1880 late enough for specialized cargo manifests?  My intuition would be to include as the last hull/hold ship, although not with passenger holds.

7 must be an experimental limit. the max for a (non-train) convoy in standard is 4, i.e. hull + 3. I wasn't planning on reworking the other ships although it would be possible. Later on, ships become more specialised, and there is also the problem of freight images for the hull itself depending on cargo. Piece and cooled goods could easily be interchangeable using this model, but oil tankers should definitely be specialised. The others are somewhat a grey area.

Hmm - this is an interesting point about Experimental's higher limit for the number of trailing vehicles that non-rail convoys might have. This was raised to accommodate road vehicles, but this would unbalance this hold system. Do I need to reduce it to four for ships; or do we need to do something complicated with the coupling constraints to restrict it manually?

If the compartments are specialized for each ship, then it would make more sense to use coupling constraints. I would just divide it into the cargo hold and compartments

Ship - Cargo Hold - Compartment A (Pax 1st class) - Compartment B (Pax 2st class) Compartment C (Mail) - etc.

I was under the impression the combinations were rather arbitrary. Carpenters just built whatever the cargo required. At their destination they'd reuse or sell the wood.

Hello

This technique can also be used for aircraft that I have made​​. Some models of aircraft are in fact "convertible". Cargo space is configurable convertible aircraft and space passengers can be eliminated and replaced with space for mail or various loads.

@jamespetts

I would suggest 3 holds is quite enough for ships and planes, but the other solution is halving the capacity of each hold.

@Milko,

Which vehicles would you suggest for this sort of modification in planes?

Which road vehicles currently take advantage of this in experimental?

I would say that if we're already making a change and if it wouldn't be too much more work, it could be handy to be able to set the maximum number of vehicles on a per-type basis.

I think the only commercial jet with both passenger and cargo hold was 747-200M combi
otherwise, the majority of them are separated into classes, which would only be of interest to experimental.

That may be true on the main deck, but every almost jet aircraft's lower (baggage) deck can carry cargo containers called Unit Load Devices.  The Wikipedia article describes the various ULD sizes and even gives capacities for a variety of craft.

Ah, yes, but on commercial aircraft, the only cargo that is loaded onto passenger aircraft are checked in baggage from passengers and food. It can also include spare aircraft parts from the aircraft owner, but that is about it.

Mail, parcels and goods always get a different, dedicated cargo aircraft ride.

The 747 combi is unique in that it has both passenger and cargo holds divided by a partition.

Are you sure? I have frequently seen mail loaded onto, or unloaded from, airplanes at the airport.  Do you have a source that says that the containers we see on passenger planes are not mail and air cargo?  Because if so, please explain how the dozen passenger carriers at my local airport ever handle air cargo -- on a phantom fleet of craft we never see?

hmm, maybe it's different between different carriers and countries?

Sorry .
It possible to transport mail in a passenger aircraft.
I've seen in a documentary how mail was transported in a passenger cabin.
Edit:Is to equip all ships with the idea of The_hood?

ah, okay. Looks like I was confusing DGR CAO and checked in baggage.

Turns out that freight loaded onto PAX aircraft account for a majority of profits for airline operators.

Sorry for the delay.

Convertible planes are:
727, 747, ATR42, ATR72, BAE146 (all version).

Al the dat files contains the cargo space in tonnes, you may use the cargo space to determine the hold space based on the number of hold you want to do.
