Does Railway modelling confuse your personal circuitry ?!

I have recently had an ICD ( Implantable Cardioverter Defibrillator ) implanted as a precaution against possible cardiac arrest . Although they are designed to prevent electrical interference , it has the same type of restrictions/recommendations as Pacemakers in terms of proximity of household electrical appliances and other electro-magnetic devices. Although the manufacturer has info about some “hobby” items ( see attached file ) they unsurprisingly do not mention specifically model railway equipment , eg loco motors or controller/transformers.

 

Gievn the general advcie I think I should be safe using all equipment to a great extent ( I’d be devastated if I couldn’t !) though maybe need to keep my implanted device 6/12 inches distant from powerful transformers , but I wondered whether there are any members out there who already have Pacemakers or ICDs fitted and have had specifi advice from consultants or manufacturers which suggests otherwise. I really just need confirmation I am not affecting operation of the device by using either analogue equipment or DCC .

If you look through the classifications of risk for different devices, you will see that it is the high current (and therefore potentially high magnetic field) devices where the risk occurs. Low voltage motors and control systems such as used for model railway are going to be in the low risk category in terms of proximity.

 

But there is something relating to model railway control that I would think it wise to consult your specialist about. I have had shocks from the track: on DC control, high voltage spiking generated by some motors; and from DCC just by touching the rails, both typically only in warm weather when there is enough sweat to make fingertips that bit more conductive. Pretty confident that the implant will still function normally even in this case, but as always it is best to check when it is something so vital.

I don't know what effect model railways would have on your implant but would have thought it would be minimal, but evidently your implant has a major effect on RMweb in that you can post here without posting!

I hope you find the information you are looking for and your railway modelling continues for many years hence

Several model railway items would be worth avoiding, because of high currents, voltages or frequencies:

 

Resistance Soldering Units

Soldering Guns

Static grass applicators

Relco and similar track cleaning devices

 

Locomotive motors contain a magnet, so you should keep them 6" away as advised, whether running or not.

I don't know about model railways but I would advise keeping well away from Eurostar power cars (which are known to be able to affect some such devices if you are standing right next to them at certain parts in the power cycle although it should not normally be possible to stand in such a position) and I wouldn't be surprised if a Class 92 can have a similar effect.

Thanks for all replies so far and for suggestions as to things to avoid getting too close to or maybe using at all and will ask specifially about shocks - something I hadn't really thought about. Thankfully I don't use Relco or Static grass applicators and only use an ordinary soldering iron , but I do use a CDU for point motors though , so will look into whether they need to be avoided or just kept at a distance - would be shame if I had to stop using them after all those hours bent at strange angles under baseboards trying to screw the point motors into exactly the right position !

 

As for "posting without a post" , I'm afraid this is my very first interaction with any RMWeb Forum ( or indeed any kind of blog , twitter feed etc as depite working in IT "luddite" is still my middle name ! ) so apologies if I did something in the wrong order or inadvertently bypassed some part of the system. The great thing is to see what advice people can give and that bits working OK so thanks again .

You might find this helpful - basically you are placing a Faraday Cage around you body that will protect you from electrical interference. http://www.lessemf.com/personal.html

Thanks XF - a very interesting site - I've learnt a lot about EMF and EMI - never even thought that there would be ordinary clothes made specifically for protection against radio and magnetic waves . I know that the devices implanted already have a certain amount of shielding so its just a bit extra that would be helpful . Will certainly look into that further .
