Using this HO brass trolley is easy. Just connect it to your analog DC power source, and it'll start running. Since it's geared for fast operation, be careful when setting the speed. The trolley's painted finish looks great, but try not to scratch it. For maintenance, check the wheels regularly for wear. If you notice any excessive plating wear, it might affect the performance. The motor can make some noise, but that's normal. If the noise gets too loud, it could be a sign of an issue. Keep the trolley clean and store it in the original box when not in use to protect it from damage. When shipping, know that we pack it really well, but still handle it gently upon arrival. If you're not happy with your purchase, let us know within 30 days for a refund, just pay for the return shipping unless it arrives damaged.
