Building Loco-shed in scalable length with servo controlled doors

Building a super detailed 1-port Locomotive shed with servo control of the doors, meaning remotely controlled open and closure of doors. The $1 USD/ea SG-90 servo is a standard servo suitable for a range of applications on the Model railroad, such as turnout motor and animation of water horses, doors and coal cranes. The servos are controlled from a standard decoder, which makes installation easy and straight forward. The loco shed is based on 3D-printed plastic parts, which reduces the item cost by 30-70%.
