    Hi everyone.
    I have recently bought an old Lima SS100 Steam Sound Simulator. I know it is probably a piece of junk as I bought it for pennies on Fleabay.
    It says in the instructions that it requires connecting to my 12v dc controller to change the sound but that it also requires a 14v ac control to provide power. I have hunted round my local model shop to no avail. Has anyone got any advice for me as to how to power the bugger?

    Also, is it possible to make a train stop for say 30 seconds then continue again automatically on a small loop of track?
    I want it to dissapear into the tunnel then wait a while before coming out the other side, to give the impression of a bigger system, whilst I can fiddle about shunting on the outer track.

    Can you post a pic? We'd like to see what the "bugger" looks like.

    I think if it's looking for AC power, you could probably use the accessory power on a normal trainset power pack. They're typically between 15 and 18 VAC.

    As for stopping for 5 minutes, you might be able to adapt the Miniatronics Reversing Unit.

    If you have an MRC throttle, it will have three sets of terminals on it. One set is marked variable dc and will go from 0 to 12 volts. The second set is constant dc at @12 volts. The third set is ac at @15-16 volts.

    Thank you everyone. My mobile web connection is limited but I will post a piccy of the sound unit next week.
    Thanks again.

    Well, if you are running two trains on two different sets of tracks, may I suggest using two power packs/transformers and having one of them on a timer, such as is used by photographers in their darkrooms? Gra-lab makes a nice one with two power outlets. I don't have a photo of one, but you will find them at most photography stores.

    Good thinking Batman. lol. I will give that a bash and see what I can come up with. Thanks.

    The "stop and go" set up you talk about has been around for a while, take a look in the Walthers catalogue or their website. I believe a couple of manufacturers make products that would work.

    It sounds to me like you power it with the AC terminal on the transformer, but the variable dc terminal controls it. The sound will vary based off of the variable dc...which is what you attach to the track. The reason it sucks AC power is probably to prevent it from stealing the variable DC that is intended for you locomotives.
