Compare the best Train Sim World freight routes and locomotives for heavy haul, shunting, mountain grades, historic traction and DLC compatibility.
Our top Train Sim World freight route is Cajon Pass for modern heavy haul; Sherman Hill suits long Union Pacific trains, Sand Patch Grade has the best mix of yards and mountain work, and Clinchfield Railroad excels at historic coal operations. The standout locomotives are the ES44C4, AC4400CW, SD40-2, Class 66 and DB BR 185.
Which Train Sim World freight route should you buy?
Cajon Pass is the strongest single purchase for dedicated modern freight, but the right choice depends on whether you prefer long mainline runs, switching, historic diesels or European operations.
| Route | Best for | Principal freight locomotives | Main caveat |
|---|---|---|---|
| Cajon Pass | Modern US heavy haul and sustained gradients | BNSF ES44C4 and SD40-2 | Long climbs make some services deliberately slow |
| Sherman Hill | Very long Union Pacific trains and dynamic-brake work | UP AC4400CW and SD40-2 | Less switching variety than Sand Patch Grade |
| Sand Patch Grade | The best mixture of yards, local work and mountain running | CSX AC4400CW, SD40-2 and GP38-2 | Cab setup and brake release can catch new drivers |
| Clinchfield Railroad | Historic coal trains and classic Appalachian operations | EMD F7 and SD40 | Choose it for period traction rather than modern power |
| Tees Valley Line | British industrial freight and classic diesel driving | BR Class 37/5 | Shorter and lighter in scale than the American routes |
| Main-Spessart Bahn | German electric freight, gradients and banking | DB BR 185.2 | It is a mixed-traffic route, and German safety systems add workload |
The choice between Cajon Pass, Sherman Hill and Sand Patch Grade comes down to service style. Our comparison of the leading American freight routes covers their gradients, traffic and driving character in more detail.
For Union Pacific, Sherman Hill is the better first purchase for mainline heavy haul. Cane Creek offers slower, methodical branch freight through striking terrain, but its service patterns are more limited; our guide to Union Pacific routes and locomotives explains the available combinations.
Main-Spessart Bahn is our freight-focused German choice because gradients, electric braking and banking duties make train handling matter. Other German routes gain useful freight traffic through timetable layers, so check the German route and locomotive compatibility overview before buying extra traction.
What are the best freight locomotives?
The ES44C4 is our leading modern heavy-haul locomotive, while the SD40-2 is the most versatile choice for learning classic North American freight operation.
- ES44C4: Best for modern BNSF heavy haul on Cajon Pass. Its strong dynamic braking is essential on the descent, but braking still needs to be planned well before a speed restriction.
- AC4400CW: Best for sustained heavy-haul work on Sand Patch Grade or Sherman Hill. Operator-specific versions do not automatically substitute into every timetable.
- SD40-2: Best all-round classic US diesel. It works well in multiple-unit consists, road services and lighter duties, though several locomotives are needed for the heaviest gradients.
- GP38-2: Best for yard switching and local freight. It is easier to manage in confined yards than a large road locomotive, but it is not the first choice for a loaded mountain train.
- EMD F7 and SD40: Best historic American pairing. Clinchfield uses them for loaded and empty coal workings where speed is less important than careful train handling.
- BR Class 66: Best modern British freight locomotive. Its value depends heavily on which routes and timetable layers you own; for example, our East Coast Main Line freight coverage explains its optional services and railhead-treatment work.
- BR Class 37/5: Best classic British freight diesel, especially if industrial workings appeal more than high-speed mainline running.
- DB BR 185: Best introduction to German electric freight. It combines regenerative or rheostatic braking with PZB, Sifa and route-specific operating rules.
- BR 193 Vectron: Best modern European alternative where a supported add-on and timetable substitution are available. Check its route requirements rather than assuming it will receive services everywhere.
Do locomotive add-ons work on every freight route?
No. Train Sim World locomotives only receive authored timetable services on routes that explicitly support that locomotive, substitution or content layer.
A mistake we see constantly is buying a locomotive first and only then discovering that its useful timetable requires another route. Check four things before purchasing:
- Required route: Some locomotive packs require a particular home route, even when the locomotive can also appear elsewhere.
- Timetable layer: Owning the locomotive may unlock extra services, but only on routes programmed to use that layer.
- Game and platform compatibility: Confirm that both the route and locomotive are supported by your Train Sim World release and platform.
- Free Roam versus Timetable Mode: Free Roam permits broader train placement, but it does not create a complete timetable, suitable wagons or authentic traffic automatically.
Different operator variants also matter. A Union Pacific AC4400CW, for example, should not be treated as an automatic replacement for the CSX version simply because the locomotive model is similar.
Which freight route is best for beginners?
Sand Patch Grade is the best learning route because it provides switching, yard transfers and road freight without locking the driver into one operating style.
Start with GP38-2 yard or local work, then move to SD40-2 road services before tackling the heaviest AC4400CW trains. Choose Cajon Pass instead if modern BNSF heavy haul is the main attraction, but expect its long descents to expose poor brake management quickly.
Tees Valley Line is the more approachable British option. Main-Spessart Bahn is rewarding once you are comfortable with PZB, Sifa, electric braking and German signal conventions.
Why will a loaded freight train not move?
Most apparently powerless freight trains are still held by the brakes. Release the automatic train brake, check the independent brake, and allow time for brake-pipe pressure to recover through the full consist before applying power.
On American locomotives, lead/trail configuration, generator-field controls and distributed-power settings can also prevent correct operation. Follow the locomotive-specific tutorial rather than copying the setup from another diesel. Apply power gradually on a gradient: jumping straight to full throttle can produce wheelslip or severe coupler forces, while dynamic brakes become progressively less effective as speed falls.
