Playing with model trains is a great hobby for people of all ages. You can enjoy running the trains in the house or keep the action outside in the backyard. While running trains outdoors can be exciting and offer a more realistic experience, it also comes with risks. Your models can be prone to damage from rain, sun, dust, and moisture. Minor issues can grow into large problems over time. That is why waterproofing matters. With some good practices, you can keep your trains safe, prolong their life, and maintain a new look.

Why Weatherproofing Your Model Trains is Important?
Weatherproofing is the protection of your trains from the weather. Sunlight can fade paint and degrade plastic. Moisture causes rust on metal parts. Sunlight fades paint and weakens plastic. Dust and dirt can interfere with movement and impede the smooth running of trains. Between maintaining and weatherproofing, you bypass the damage before it ever even happens. This not only saves money but keeps your library going year-round.
Guide on Waterproofing Your Model Trains
Step 1: Clean the Model Trains
Cleaning is the first process in weatherproofing. Protective coatings can become ineffective when they’re covered in dust and dirt.
Wipe the body with a soft cloth. If you find tiny cracks, use a small brush or cotton swab. Stay away from harsh chemicals. It can harm the paint job and decals. Clean trains also look better and are easier to maintain.
Step 2: Seal the Body
After the cleaning is done, seal the body of your train. A transparent spray sealant will prevent the paint from fading in the sun. It also helps to create a layer against moisture. Keep the spray away and do a light, fine, even coat. Allow it to dry and then apply another coat. Generally, two or three thin coats are applied for the best results. Always opt for the model sprays rather than household sprays, which can be too heavy.
Step 3: Cover the Wheels and Mechanism
Metal wheels and gears were the most prone to rust. Keep them oiled or lubricated to prevent rust. There are ones for model trains that are safe and work very well. If you put too much oil on it, it will just attract dirt, so use very, very little oil. This prevents your train from running roughly and parts from becoming entangled with or adhering to each other.
Step 4: Cover Electrical Parts
Water can cause electrical components to fail. To avoid any issues, tape over (or cover with waterproof covers) exposed wires and joints. Ensure the motor is safe, but open to good air flow.
Step 5: Store the Trains in a Safe Place
Even if you have waterproofed, you might still care about storage. Never leave your trains outside in the rain or sun unprotected for extended periods. Keep them well-arrested in a dry box or case. Include silica gel packs to soak up moisture. A safe place to store your trains will help to keep your locomotives running their best.
