2 speed or by the filling height of the ore in the reservoir of the train loading station. Currently to maintain bulk rail car loads and in particular bogey loads below certain limits, the maximum load per bulk rail car is limited underneath the provided maximum capacity of the bulk rail car and thus the 6 optimum of loading the bulk rail car is not reached. On the other hand, overloads are currently treated by stopping the train again and using a construction industry type excavator to remove bulk material from the bulk rail car again, to avoid overload of the bulk rail car or of the bogeys of the bulk rail car. For this propose a scale is provided downstream the outgoing side of the train loading station but upstream the excavator position in order to provide information for a person who operates the excavator to load and unload the bulk rail car by means of adopted mass quantities of bulk material.
Currently train loading is controlled to limit total axle loads of bulk rail cars to prevent localised loads on bridges of the railway and the track exceeding the design limits. Due to the above said variances in the loading practices, which is a combination of variables such as height of the bulk material in the bulk rail car, train speed, density, granularity, bulk size distribution in particular of lumps and fines, the repose angle and the bunker filling height.
The variance typically range from 0,2 tons to 5 tons depending on these variables. Bogeys are weighed on the track scales approximately two bulk rail car length from the outgoing side of the train loading station. The activity to remove overloads leads to longer train loading times and train cycle times to unload, in particular by using an excavator for unloading peak loads. Accordingly, it is an objective to remove the arising time delay to both loading and consist cycled times.

5 The core idea of the present invention is to provide a load manipulating station which can be operated automatically and/or without an operating person. The data input to the load manipulating station comprising e.g, a load topography representing the filling height in the bulk rail cars and the weight of the bulk rail cars with a scale is sufficient to control the load manipulating station in a way, to avoid an overload of the bulk rail cars in total and to avoid different loads of the common bogeys of one single bulk rail car.
io The special construction of the load manipulating station comprising manipulator tracks and comprising a portal unit which is movable arranged on the manipulator tracks enable a bulk material manipulator to unload and load bulk material out of and into the bulk rail cars in an easy manner. By 15 means of the manipulator tracks which extend along the traveling direction of the bulk rail train the portal unit can move corresponding to the travel movement of the train, in particular with the same speed, and the unloading and loading of bulk material out of and into the bulk rail cars is achievable without influencing the travel speed of the train which is in particular 20 adopted to the necessary travel speed of the bulk rail train passing through the train loading station. On the other hand, the train travel speed through the train loading station can be increased, because the extensive measuring algorithm with influencing the load distribution of the bulk material within the bulk rail car according to WO 2015/003776 Al is no 25 more necessary.
According to a preferred embodiment the portal unit comprises a bulk material bunker for temporarily storing bulk material, in order to receive bulk material removed from the bulk rail cars and/or to provide bulk material for 30 loading back into the bulk rail cars.

In this context it is conceivable that the bulk material bunker features a longitudinal extension along the extension of the manipulator tracks and the extension of the railway, respectively.
The bulk material bunker according to a preferred embodiment is formed by a bin or a container which is arranged on or in conjunction with the portal unit and the manipulator can load and unload bulk material Into and out of the bulk material bunker.

The portal unit can be based according to a preferred embodiment on a manipulator crane, or alternatively on a gantry crane with or without pillars or other structure, but the manipulator tracks are arranged on pillars only as a preferred embodiment and form overhead tracks. The portal unit is movable above the bulk rail cars of the bulk rail train. In particular the bulk material manipulator is arranged above the bulk rail cars of the bulk rail train and according to a preferred embodiment the bulk material bunker is also arranged in a height above the bulk rail cars of the bulk rail train.

7 According to yet another embodiment beside the railway for the bulk rail train a bypass unloading section is arranged, whereas the portal unit is performed to unload bulk material within the bypass unloading section. The bypass unloading section is accessible for trucks and the portal unit is performed to unload bulk material to the trucks. In particular in the case when a huge number of bulk rail cars are overload with bulk material by passing the train loading station, the load manipulating station can transfer the overload amount of bulk material via the bypass unloading section into trucks and e. g. the train loading station may feature a truck unloading station for transferring the bulk material from the trucks back into the train loading station refilling the reservoir.
According to another preferred embodiment, in conjunction with the bulk material bunker a first conveyor means is arranged for loading bulk material from the bulk material bunker into the trucks. The first conveyor means gets activated when the bulk material bunker is filled up to a limit and the bulk rail cars running into the load manipulating station are still overloaded.
Moreover, the portal unit comprises a grab bucket, clamshell bucket, a vertical axis rope hoist or a vacuum feed unit forming the bulk material manipulator for unloading bulk material out of the bulk rail cars. According to another advantage, the bucket, the vertical access rope hoist or any other kind of excavating means may contain a load scale in order to provide an information of the mass of removed bulk material out of the bulk rail cars and transferred into the bulk material bunker with each movement of the bulk material manipulator. This load scale data can be fed to the train manifest to document the manipulated weights before sending out the resulting corrected manifest to the rail network operator, the customer or the port.

8 In conjunction with the bulk material bunker a second conveyor means is arranged for loading bulk material from the bulk material bunker back into the bulk rail cars if necessary. This has the advantage that bulk material can be transferred from the bunker into the bulk rail cars in an easy manner and with an appropriate dosage, and the use of a conveyor means for transferring the bulk material back into the bulk rail cars can be operated quickly and reliable.
In conjunction with another preferred embodiment the portal unit comprises io a portal frame and a trolley, whereas the portal frame is movable arranged on the manipulator tracks parallel to the bulk rail train and the trolley is movable arranged on the portal frame in a cross direction relative to the bulk rail train. For example the portal frame can be moved along the manipulator tracks by means of rollers, and the trolley can be moved on the portal frame with another set of rollers, and the moving direction of the portal frame on the manipulator tracks and the moving direction of the trolley on the portal frame are arranged perpendicular to each other.

9 and below the arrangement of the bulk material manipulator, the unloading station is placed which is accessible for trucks.
With respect to the operating strategy of the load manipulating station it is s also conceivable that bulk material which has been unloaded with the bulk material manipulator e.g. formed by a shovel can remain in said manipulator until at another point within the same bulk rail car or in a subsequent bulk rail car said bulk material must be re-loaded back in order to reach the required weight or to harmonize the bogey load of the front or the back bogey.
According to yet another embodiment at least one load profile sensor is arranged upstream the bulk material manipulator for sensing the bulk material load topography within the bulk rail cars. This load profile sensor may be formed with a radar or laser sensor providing a kind of a sensor curtain in order to provide topography data of the bulk material loading height within the bulk rail car. According to yet another embodiment, at least one track scale is arranged upstream the bulk material manipulator for sensing the bulk material load weight within the bulk rail cars.
The heart of the system may be formed by a control unit which is provided for controlling the load manipulating station depending from date received from the load profile sensor sensing the load topography and from the scale sensing the load per bogey of the bulk rail cars. The control unit can operate the system without the need of an operating person, and the system may be operated with the control unit automatically. As a preferred embodiment, a supervisor person may supervise the operating of the system by means of the control unit, which may feature an appropriate control interface.

10 Within the spirit of the present invention the control unit may be interconnected with the train loading station, and when the control unit measures a continuously overloading of a huge number of bulk rail cars, the control unit may provide a signal to the train loading station to downscale the average load of the bulk rail cars. In the other way around if the control unit measures a continuous underloading of the bulk rail cars, the control unit may provide another signal to the train loading station to enlarge the loading of the bulk rail cars. With this system is formed a closed loop control circuit between the load manipulating station and the train io loading station with the result, that no or only a few trucks may transport bulk material from the load manipulating station back to the train loading station on the one hand and on the other hand the loading of the bulk rail cars is only slightly underneath the maximum allowable load of the bulk rail cars. Another improvement is the homogenous load of the bogeys of each bulk rail car of the bulk rail train.
The present invention is also directed on a method for manipulating the load in bulk rail cars of a bulk rail train, which bulk rail cars are loaded with bulk material like coal, ore, burden material or the like by means of a train loading station, wherein the method comprises at least the following steps:
