SBB LRZ - 1
SBB LRZ - 1
Here’s my rendition of a single unit of SBB’s firefighting train.
Given the time constraints of the challenge, I knew that I would only be able to complete one unit of the LRZ consist. Therefore, I chose the largest unit with a water cannon. I would need the space to house, the battery/receiver, pump, water tank, drive motor, and cannon rotation mechanism. I began the design in LDD and quickly drafted the frame, cab and container. This gave me a rough idea of the space I had to work with. I tried to position the pump motor as low as possible to allow for the maximum amount of height for the cylinder. Since there was only one option for the drive motor placement and cabin space was already limited, the placement of the cannon rotation mechanism and drive motor had to be placed in the container. Due to the vertical distances between the cannon rotation motor and cabin, I opted to use a pulley system because the string could be guided through a series of holes to account for the vertical displacement.
When I eventually started building the model IRL, I encountered some unexpected setbacks; namely two parts I had used did not exist in the colors I had used in LDD. This required some time to redesign. In addition to a bricklink kerfuffle, I had lost valuable time to complete the model. I prioritized functionality over aesthetics and realism.
