Sound For The Auscision 49

A few weeks ago a nice big parcel arrived in the post and this contained a NSWR 49 class locomotive from Auscision in 1:43.5. I had been looking forward to the arrival of this locomotive but I wouldn’t exactly say I was “hanging out”. It’s not exactly my favourite prototype and doesn’t really fit my era but it does fit a niche in my roster that needed filling till something more suitable comes along, or gets built! 🙂

It needs a DCC sound decoder and some weathering but it's nice to have something to put on the tracks that's pretty much ready to go. This photo shows the 49 with a pair of Protocraft couplers installed.

Generally speaking the loco is nicely detailed and beautifully finished and is a significant improvement on the KHIAC 44 (same company, dumb name). It has a large Buehler can motor centrally mounted driving bogie mounted gears through twin flywheels. There was a lot of internet chatter after the loco arrived about the damage caused to the cab’s rear vision mirrors by the less than adequate packing but I found that it was a simple job to repair this damage.

I installed a pair of Protocraft type E couplers and decided to install a sound decoder straight away, although the likelihood of this loco getting a decent stretch of the legs any time soon is fairly remote. Maybe the Arakoola guys will let me run it at the upcoming AMRA Liverpool exhibition in October? 🙂

The decoder question had been exercising a few minds after we actually got our hands on the 49 and a secret cabal that I’ve tagged the Dead Decoder Society (in honour of Robyn Williams’ recent passing) has been formed to try to cram our standard choice of an ESU Loksound XL v4 into the thing. There were those who were afeared that this decoder, with all its chest thumping grunt, wouldn’t fit but it does and I have a photo to prove it.

It's a tight fit but a Loksound XLv4 does just fit into the body of the 49. The black box on the left is not the flight recoder but an enclosure for the speakers. The speakers are Jaycar part #AS3030.

Another factor that caused a small modicum of consternation was the absence of our DCC install guru, I’ll call him Mr Myagi to protect his identity, who chose the week of the 49’s arrival to go off on holiday! Don’t panic, don’t panic! Upon his arrival home said guru set to work designing some circuit boards to aid the installation of the XL decoder that will allow all the lights to work, the whistle to operate, but sadly not the bell to tinkle. We don’t use bells in NSW 🙂 Following carefully in Mr Myagi’s footsteps I’ve managed to construct the circuit boards and build a small black styrene box to enclose the Jaycar speakers.

All has been going along nicely but the next step is to start hooking up the LED lights. This is a sometimes fraught process as it can be devilish hard to determine cathodes from anodes, well it is for someone as electronically illiterate as me. Mr Myagi has suggested gently removing the LEDs from the body, thus easing the wiring up process. However he managed to fry four of the LEDs early on so he was going to have to remove them anyway to replace them in the specimen he’s working on. Did I mention the four blown LEDs? Wax on, wax off Mr Myagi! Wax on indeed… 🙂

If it’s possible for our resident DCC guru to fry a few LEDs along the way it gives me heart that I may be able to get through this installation process in one piece. Let’s hope the decoder does too!
