19 kilometres, 33 stops, and paused for more than a year: What happened to Hamburg 172 for LOTUS?

When we last reported on Citybus Hamburg in September 2025, the project had already been unusually quiet for several months. The publicly visible status has barely changed since then. The DLC remains listed on Steam, can still be added to the wishlist, and continues to have no release date. No new screenshots, revised roadmap, or specific announcement about a restart of development has been published. What began as a temporary quiet period has therefore become a pause lasting for more than a year.

However, it is not entirely correct to say that there had been no sign of life at all since the beginning of 2025. On May 4, 2025, developer Darius Bode responded in the official LOTUS forum to a question about whether work had been stopped because of the redevelopment of the main game. His answer was clear: Development would be paused until a stable and secure foundation was available. At the same time, he explained that object construction was already far advanced and that the DLC could then be completed quickly.

This statement remains the most important official indication of the project’s status. It initially means that Citybus Hamburg has not publicly been described as cancelled. The pause was explained by the technical foundation of LOTUS, not by a final end to the project. At the same time, a pause without a date is not a real release perspective. As long as it is unclear when the required foundation will be available and when active work will resume, no serious release window can be given for the DLC.

That is exactly why it is worth taking another look at what was originally planned. Citybus Hamburg is intended to recreate Hamburg bus route 172 as it operated in 2005. The approximately 19-kilometre route includes 33 stops and travels through different parts of northern Hamburg. The major roads of Uhlenhorst, the narrower one-way streets in Barmbek, and the journey to Fuhlsbüttel Airport are all mentioned. The project therefore combines dense urban areas, residential streets, important transport hubs, and the airport within one connected route.

The year 2005 is more than just a number in the product description. The selected period determines the vehicles, streetscape, advertisements, signs, traffic lights, AI traffic, and many small details in the surroundings. Hamburg in the early 2000s does not look exactly like the city today. This creates the special appeal of the project: Citybus Hamburg does not want to recreate a current route with modern vehicles, but a specific historical state.

More than 1,100 unique scenery objects in a Hamburg style were announced for this recreation. These presumably include not only prominent buildings, but also smaller elements that make a route recognisable: facades, stop areas, street furniture, vegetation, and typical urban objects. The official description mentions high-resolution textures, custom tree and vegetation models, and new AI vehicles from the early 2000s with different colour variants and optimised levels of detail.

This number shows why the statement about the advanced object construction matters. More than 1,100 individual objects are not created casually. If a large proportion of them has already been completed, the project probably contains a considerable amount of work. However, this does not automatically mean that the entire DLC is close to release. A route does not consist only of objects. Roads, junctions, traffic logic, stops, timetables, vehicle systems, optimisation, testing, and integration into LOTUS also have to work together.

Advanced object construction can therefore mean that many visible foundations already exist. However, it does not reveal which proportion of the remaining production is finished. Without new information, it would be unreliable to derive a percentage or possible release date from it. This remains one of the greatest problems created by the long pause: The community knows that a large amount of material exists, but cannot judge how far the project actually remains from a complete playable package.

There is now more clarity about the vehicle than there was in older reports. The official announcement in the LOTUS forum names a 1992 Mercedes-Benz O 405 N as the highly detailed service bus. This fits the setting in 2005 and the announced first generation of low-floor buses in Hamburg city transport. While the Steam page still refers only generally to a highly detailed low-floor bus and promises further information, the official forum announcement names the specific model.

Many questions about the O 405 N nevertheless remain open. The developer already explained in 2024 that modules were planned, but could not promise how extensive that support would become. Which equipment versions, functions, sounds, or operational details the final version is intended to receive has still not been described completely. The vehicle is therefore named, but its final functional scope remains open.

Authentic timetables and vehicle workings with short workings and different termini were also planned. This matters for a single route because not every service would necessarily have to travel from the first to the last stop in exactly the same way. Different workings can create variety, use turning points differently, and represent everyday operations more convincingly. Route 172 was therefore intended to appear not only as a 19-kilometre corridor, but as a complete operating schedule with several variations.

These details explain why many bus fans paid attention when the project was announced. Darius Bode is known for earlier Hamburg projects for OMSI, and a route with a real-world counterpart, historical setting, and suitable low-floor bus covers an area that is not often recreated in current bus simulations. Hamburg 172 did not promise a huge fictional map, but a clearly defined and carefully constructed route with strong recognition value.

According to the official statement, the reason that this has not yet become a playable product is not simply a lack of objects. The add-on is waiting for a stable and secure foundation in the main game. This sentence demonstrates the special dependency of external expansions. An add-on developer can make significant progress on the route, buildings, and vehicles. If central technical requirements of the main program change or are not yet reliable enough, the final integration still cannot be completed sensibly.

This caution is understandable for a paid DLC. A product should not be released on a foundation where important functions are uncertain or may need to be adapted again later. At the same time, the risk is transferred to the developer and the waiting community. The longer the technical foundation remains open, the longer already completed content remains unused. Work does not automatically become outdated, but textures, models, scripts, and expectations may require additional adjustments over time.

The Steam page continues to describe Citybus Hamburg as a product in an Early Access state whose content is intended to grow together with LOTUS Simulator. Future engine functions such as seasons, water, and expanded terrain design are mentioned. However, the DLC has not been released at all. This creates an unusual situation: An unavailable add-on is already being described as a growing Early Access project even though the starting point of that growth still does not exist.

This approach can make sense in principle when a base game is still being developed heavily. An add-on could initially appear with a solid core and later adopt new technical possibilities. For buyers, however, it would be essential to know clearly which content is available at launch, what will follow later, and which functions depend on the development of the main game. This transparency is currently missing because neither a date nor an up-to-date functional status has been provided.

The long silence does not automatically mean that nothing is happening behind the scenes. Developers can work on objects, concepts, or adjustments without regularly publishing screenshots. In the case of Citybus Hamburg, however, development was explicitly described as paused. It should therefore not be presented as though the project were simply continuing quietly and according to plan. The last confirmed status is an interruption, not active production.

It would be equally wrong to declare the DLC permanently failed. The Steam page remains available, the product has not been officially cancelled, and the developer explained that the far-advanced object construction could allow comparatively rapid completion once the foundation becomes stable. This statement leaves the door open. However, it does not guarantee that the restart will happen soon or that all previously planned content will remain unchanged.

Communication is therefore becoming increasingly important for public perception. Nobody should expect weekly development diaries from a small add-on team. After more than a year of paused work, however, even a short status message would be useful. Is the project still waiting for LOTUS? Are adjustments planned? Do the route and vehicle remain at the previous stage? Or have the project’s priorities changed? A clear answer would not accelerate release, but it would make the difference between a pause, redevelopment, and a possible ending easier to understand.

This is particularly relevant because expectations for Hamburg 172 became relatively specific through the early images and descriptions. Nineteen kilometres, 33 stops, more than 1,100 objects, an O 405 N, and historical timetable operations are no longer just a loose idea. They describe an extensive product that was visibly planned and partly constructed. The more specifically a project is announced, the more noticeable a long period without new information becomes.

For players, this leaves a difficult mixture of potential and uncertainty. In terms of content, Citybus Hamburg still offers many interesting elements. The route has a clear geographical progression, the 2005 setting adds nostalgic character, and the O 405 N is likely to be a particular attraction for many OMSI and Hamburg fans. At the same time, there is no price, no release date, no confirmed restart, and no current assessment of the remaining workload.

A scope centred on only one main route does not automatically have to be too small either. A single route can be more interesting in the long term than a large but superficial map if timetables, short workings, different termini, traffic behaviour, and scenery are implemented carefully. Nineteen kilometres and 33 stops fundamentally provide enough space for different urban areas and longer duties. What would matter is how varied the route actually feels during everyday operation.

The question of additional routes still remains. The Steam description focuses clearly on route 172. Whether further routes, sections, or expansions are planned later is not known in a binding form. Since the DLC was intended to grow together with LOTUS, later expansion would be conceivable in principle. However, no specific promise should be derived from that. The confirmed core today remains route 172 in 2005.

The strongest point of the project remains its clear identity. Citybus Hamburg does not want to suggest an unnamed German city, but to recreate specific streets and locations in northern Hamburg. The journey from Uhlenhorst through Barmbek to Fuhlsbüttel connects recognisable districts with a destination that is also operationally interesting. Together with historical AI vehicles and a period-appropriate bus, this could create a route clearly differentiated from modern fictional maps.

Its greatest problem is equally clear: The add-on apparently cannot determine its own schedule independently of the main game. As long as the required technical foundation is missing or not considered secure enough, even far-advanced object construction remains without a playable result. Hamburg 172 therefore demonstrates how strongly external LOTUS projects depend on the condition of the platform.

This is frustrating for fans without automatically justifying criticism of the individual developer. A small project cannot create fundamental platform stability on its own. At the same time, it is understandable that players are no longer satisfied with only early screenshots and a Steam wishlist after more than a year of paused development. Hope eventually needs new information.

The current status can therefore be summarised fairly clearly: Citybus Hamburg has not been released, still has no date, and has not officially been cancelled. The last clear statement from the developer dates from May 2025. According to that statement, work is paused until LOTUS offers a stable and secure foundation. Object construction is said to be far advanced. Whether and when this will become active development again is not publicly known.

Hamburg 172 is therefore neither a disappeared project nor a DLC whose imminent release should be expected. It remains in an open waiting state. The content plan remains appealing, but there is no reliable technical or scheduling perspective. Only a new statement from the developer or visible progress could change that.

Are you still waiting for Hamburg 172 after more than a year of paused development, or has the project moved too far away for you without new images and a clear schedule?
