The power required for total 60metres of rope would be just under 250watts, and it would need to run for 4 hours. It has been suggested that we might be able to make it work with an invertor running off a 24v lorry battery.

Although our initial plan was to use a small generator mounted in a brake van at the end of the train, the Health & Safety group are having a field day of opposition. We have found the ideal product that can be cut to length etc, but has 240v ac as power supply. As part of our improved Christmas experience we are looking to create a “train of light” with LED Rope lights running the length of our train. Good evening, I am writing on behalf of the Leighton Buzzard Narrow Gauge Railway in Bedfordshire. You’ll need to size a UPS to meet the maximum power draw expected, but calculate the runtime based upon the average power consumption. If your load varies over time, you’ll need to estimate the average power consumption. There are assumptions made on standby current consumption and inverter efficiency that will be different for different UPS and also different at different load levels. If you have 7.2Ah or 8.5Ah then if you round down this will give you a minimum, and round up will give you a maximum. If the spec of your battery is not in Ampere Hours but Watt Hours, then as a very rough guide divide the Wh rating by 4 to get the Ah. So, if you have one single 6V battery of 12Ah capacity, then you’ll need to say it’s a 12V 6Ah battery. This calculator is based upon 12V blocks only and will only accept integer values. Then you’ll need to know how many battery blocks and of what Ampere Hour capacity are in your UPS. You’ll need to know how much power (in Watts) your UPS is delivering. Need any idea how long your UPS will last for? Eg How much runtime will you get out of your UPS? Then this UPS Runtime Calculator is just what you need.
