Version 5.11

Version 5.11 is the next release of FYM, and is currently in development.

Back to Version History

Car Destinations

Historically, FYM has only assigned and stored destinations as a whole map (or, for maps with multiple IDs, individual map IDs). On arriving at its destination, a car would assign itself to a randomly chosen siding, although if the car had previously been un/loaded at the destination, it would remember the siding used.

In V5.11, we have revised the data that FYM holds about car destinations, and FYM is now able to assign cars to a specific siding at the destination. In the main display, cars will still only display siding numbers if destined for the current map, but siding numbers are now shown for all destinations in the train information window, and can be filtered by in custom Classification Sorts.

When selecting a car destination manually, the dropdown will be populated by siding, rather than map. Note that virtual maps do not have siding numbers, and some other car destinations will not have them (intermodal terminals or older maps where siding numbers were not used for all sidings):

When viewing a train in the Train Information window, siding numbers for all destinations are shown in the "P"ool column, not just the current map:

This allows some new bits of gameplay and functionality:

Blocking by siding

In some cases, local trains need cars sorted in a certain order - either because of very limited switching space, or because some sidings are only accessible in one direction. For example, a local may run A-B-C-B-A, serving some sidings at B on the outbound trip, and others on the return. Now that FYM is always aware of the final destination sidings, cars can be sorted by their destination siding at maps other than the current map using custom Classification Sorts.

Siding weights

FYM now stores information about how busy each siding is in real life, with this weight determining how likely a car is to be sent to the siding. This allows us to distinguish between things like busy chemical plants and minor fertilizer terminals, between maps with one industry and maps with dozens, and also to prevent random carload traffic being sent to inappropriate places (many coal mines only load unit trains, for example). Previously, this was all under the control of players, and while many have put in great effort to recreate realistic traffic patterns, it has proved difficult to make those traffic levels consistent across maps, and also to ensure that new maps get reasonable traffic levels, both of which have led to maps being unpopular due to very high or very low traffic levels. With the advent of virtual maps, which often cover a large number of

Regardless of the assigned siding weight, players are still free to assign cars to any destination.

Prevent cross loadings

Many sidings in FYM are served by multiple railroads. For example, many sidings in California are served by both BNSF and UP. If a car is loaded at one such siding with a destination on BNSF, it would be ridiculous (and, in real life, more expensive for the customer) for the car to be routed via UP for interchange to BNSF when the car could travel solely on BNSF. Now that FYM is aware of the railroads serving every siding, it will restrict these sorts of "cross loadings", so that cars automatically choose a sensible route.

Train Information Window layout and wording changes

The Train Information Window has been very crowded for some time, particularly the bottom control panel. Additionally, the window used the term "Bill" in an unrealistic sense to refer to cars assigned such that they return to the same origin repeatedly. This terminology has been replaced by "Car Pools", with what was once a "billed car" now being "a car assigned to a Shipper Pool".

This has been revised into four sections:

• Destination, covering the selection of car destinations and assignment of siding numbers

• Load, allowing different car loads to be assigned to a car

• Car Pools, covering what was formerly "Bill", as well as some new functionality

• Repair, covering new car repair functionality.

Buffer and Spacer cars

Unit trains often require buffer or spacer cars to ensure safe transit, and these are now more fully represented in FYM. Cars can be assigned to these purposes in the Car Pools tab of the Train Information Window. In order to be assigned to buffer or spacer car service, a car must be empty and unassigned. A car can only be removed from buffer or spacer car service through the Car Pools tab, preventing cars being accidentally assigned to other destinations, an issue that has often occurred in FYM.

A buffer car is a car placed between the locomotives and hazardous goods, to provide some protection to the locomotive and crew in case of a collision or derailment. Buffer cars are commonly covered hoppers filled with sand, or tank cars filled with water. FYM will automatically add a load to buffer cars to represent this.

A spacer car is an empty car used to protect abnormally sized loads, most commonly empty flat cars used in the transport of windmill blades, but spacer cars may also be used in carrying abnormally heavy loads to distribute weight. In the case of windmill blades, these exceed the length of the longest flat cars, and so an additional flat cars are placed at either end of the load to ensure there is sufficient space between loaded cars.

In this unit train, a brown covered hopper is being used as a buffer car.	Spacer cars used in wind turbine blade transport. Each blade is loaded across three flat cars, with the central car not actually carrying the blade at all.

Car repair

Car repair (bad order cars) have been in FYM for a very long time, but have not been a major part of gameplay. In particular, maps with car shops have seen very little use, with no particular reason to send cars to them. This functionality has been expanded to give cars two different repair states: "bad order", and "home shop for repair". FYM is able to dynamically generate these states, and the rates of cars needing repair have been increased and are now triggered by many activities. For example, cars arriving at a major yard will be more likely to be bad ordered as carmen find defects on inspecting the train; industries can reject a car for loading after finding it in poor condition; and cars can be sent for repair or refurbishing after unloading.

Bad order

The bad order state represents a car with a dangerous defect that must be rectified as soon as possible. As before, this is indicated by the color red, flashing red in the 4 filter in map. Cars will now display "Bad Order - To Repair Track" more prominently in the Train Information Window.

In the real world, almost all bad order cars can actually be repaired on site as long as suitable equipment is brought. Short spur sidings for setting out bad order cars for repair can be found at many locations, particularly along busy main lines and at facilities like power plants, coal terminals, and other unit train destinations. FYM now has the ability to simulate calling out a repair crew, with a new "Emergency Repair" button in the "Repair" tab of the Train Information Window. In order to use this, the car must be bad ordered (a "Home Shop for Repair" car cannot be emergency repaired) and left stationary and uncoupled from any other cars. After a delay, the car will be returned to service.

Home shop for repair

A car that is assigned to its Home Shop for Repair will be allocated to a specific car shop in the FYM network, and this will be considered the car's destination until it has been repaired at that shop. A car in this state is safe to move, but needs some form of major work (repair, refurbishment, or inspection). This car shop may be owned by the car's owner (particularly for tank cars), or may be a third party contract shop with appropriate skills and facilities (and a competitive rate for carrying out the work!).

Such cars are indicated by an orange marker (in place of the red for bad order cars), and a shop destination shown in italics. FYM's sorting logic will automatically treat the car as being destined for this shop. On arrival at its destination, the car must be sent to a repair track, at which point it will revert to normal service. It is possible for cars to be sent to a virtual map ID for repair if a contract shop exists at such a destination; sending the car to local delivery like other cars for the virtual map will cause it to be repaired.

Note that it is possible that when a car is damaged in some way, it will first require an emergency bad order repair to make it safe to travel, and then to travel to a home shop for more complete repairs. FYM will handle these states automatically.

Map rotation

It is now possible to rotate your view of a map by holding down the middle mouse button and dragging left and right. When dragging, the view is slightly "sticky" at 45 degree increments. The Home key will return the view to the default orientation for the map.

(We are aware that FYM does not look particularly good at most angles other than 90 degree increments, and that zoom would also be a useful feature, but these require significant revisions to FYM's original graphics engine - we hope to find the time to do these one day!)
