The concept of my proposal is to create a transformable and changing space. Well, I have decided to merge this concept with the concepts of my other two proposals, which consisted of a natural space and a diaphanous space within what is a place as small as a train carriage. In short, the design of this wagon will be solved by creating a transformable, ephemeral space, a natural space in which we will find curved shapes which will generate a sense of movement and a diaphanous space through resources such as using a mirror that increases the space and gives that feeling of infinity.

The transformable space is resolved by creating two different spaces inside the train car: I have designed some fixed structures that surround the walls and ceiling using them for the extrapolation of the train tracks simulating what are the sleepers while I have used a light fixture to simulate the rails. From these same structures are born some seats which depend on a mechanism of rails on the floor of the wagon that allow to be placed one behind the other to attend in the moments that the conferences are given, these have different heights being the one at the back of the wagon the smallest and the first the highest, creating a decrease in the size of the seats in order to have the maximum visualization. I have merged this rail system with another one which allows us to turn the seats so that they would be at the sides of the carriage, allowing passengers to maintain a closer contact between them when holding meetings. At the back of the wagon I have placed a conference table with dual functionality as it would serve as a furniture collector of all seats.

To create the natural space I have chosen to include curved shapes in the design of the room. These are found in the fixed structures, in the way the seats are born from them. For an even greater sense of spaciousness I have used a mirror on the back wall of the carriage, which means that when we enter the carriage we perceive that it is infinite due to the continuous repetition of the fixed structures. The fact of having a mirror in front of our eyes and having that image of infinity constantly repeated during the lectures can be uncomfortable so I have also used a system of movable panels which will cover the mirror while the lectures are given.

As for the lighting, I have opted for a Neutral Glow light tone which is exclusive for offices, receptions... In the design of my carriage the lighting is a key point, as I have decided to use luminaire along the entire length of the carriage on the floor diffusing it on the sides. For the lining of the walls of the train I have opted for a material such as wood chipboard in white which I use in a curved shape being sectioned at the ceiling, leaving a gap in the ceiling which is covered by a white mesh.
