Default Aristo-craft Train Engineer Transmitter CRE 55470

As the title suggests I am after the repair of an Aristo-craft Train Engineer Transmitter CRE 55470. Don't know much about Rx/Tx, however it is a 27Mhz system that controls train power supplies, it's broken into 10 frequencies and then 10m channels.

I bought the system second hand, and the faulty handset came as a free addition, I was informed that it would not "bind", this hand set has an off switch and auto shuts off, but after one week not switched off the new batteries were completely flat.

Can anybody provide assistance or direct me to assistance.

Many thanks Jim B

Sadly it seems that nobody here is able to assist me with my repair, if anybody could provide details of a commercial venture that maybe able to assist I would very grateful.
Many thanks.

It may simply be something no-one else on here has ever come across. I don't know whether you're talking about a piece of equipment for use on full-size trains, or on models. The word 'engineer' associated with anything railway either sounds American or refers to Mr Brunel

Some photos might help stir some thoughts.

It is for model railways, there is at least one for sale on eBay at the moment, but I'd think that any member in a position to help would have responded. You may need to contact the distributor, if there is one in the UK.

David, many thanks for the steer (pun intended), I will look to post photos.

Bill, many thanks, I do keep an eye on ebay, and the last one I saw was in USA. Sadly these are no longer sold and the manufacture has gone as well, so no source to go back to, hence my use of this site hoping somebody could provide some direction. I would have hoped that somebody with knowledge of the workings, maintenance and repair of 27 Mhz transmitters could have helped

Jimmy, Pictures and a copy of the circuit diagram would help. 27MHz is at the top end of the HF(Short Wave) Band. Some amateur radio guys might be familiar with your circuitry. I know nothing about model railways, but you mentioned 10 frequencies & then 10 channels, so some sort of FSK or complicated modulation might be involved. Us lot, being mainly "vintage", are more likely to be familiar with just CW, AM or SSB, or FM transmitting circuitry.

Is there not a Model Railway Forum out there on the internet ? Or a club somewhere near you ?

Regards, David.

David, it was a model railway forum that pointed me this way, I don't have a circuit diagram though I will enquire, however this link should take you to the manual:

Photos of the item:

Hope this helps, thanks

OK, full circle it is

So can I assume you've also tried the Aristo Craft forum? http://www.aristocraftforum.com/index.php

Re the document in David's post - Crest Electronics closed down in 2016.

The 27MHz technology is all similar. I don't think 75MHz is a UK approved frequency.

These might be worth trying, they are located in the south west;

Thanks guys, a couple of more leads to follow. I am sure I am not the only person who needs one of these items repaired, I will keep the forum updated for any future needs.

I have looked at the forum and identified a source in the USA for repair, awaiting response, I have also contacted RC Hobby Store, and had a positive response from Graham, so things are looking up.
