Loading head arrangement including sealing at the loading opening of a railway car

A loading head arrangement, including a ventilation hood for ventilating railway cars loaded with pourable bulk materials, the ventilation hood sealingly resting on a ventilation opening arranged at the railway car by way of at least one seal, characterized in that the seal is designed as a double seal and has a first upper sealing ring, which rests on a horizontal flange of the ventilation opening, and a second lower sealing ring, which sealingly conforms to a vertical flange of the ventilation opening.

A method for operating a loading head arrangement, including a telescopic loading head for loading pourable bulk materials onto railway cars, characterized by the following method steps:

• in a first method step, lowering the loading head by way of lifting gear onto a filling opening arranged at the railway car until a lower sealing ring, at the loading head, moves into the filling opening and sealingly conforms to a vertical flange of the filling opening, and becomes centered there;
• in a second method step, lowering the loading head further by way of the lifting gear until an upper second sealing ring rests on a horizontal flange of the filling opening and provides sealing there.
