Class 121

Recommended Posts

Does the sound not also depend on the exhaust arrangement? Or the body around the engine? Where do you stop? Very different sound from a C compared to a 181, despite both having an 8-645.

Small differences can have quite an effect on sounds. People who rode motorbikes in 70s may remember how about 25% of Allegros had an aerodynamic whistle from the front bodywork. And the AW Argosy had a very distinctive sound, marking it out easily from all other Dart-powered aircraft.

A's and C's had different exhaust arrangement, so as you say the sound was a lot different. GM built locos have GM exhaust arrangements so they do sound a lot more similar to each other. The A's and C's were exceptions of course.

 

Anyway, we're wandering way off topic! :)

So existing 141 sound projects will do perfectly for early 121s and existing 181 sound projects will do for later 121s. Special 121 sound projects NOT needed at all at all! :) I can't tell any difference listening to dozens of youtube clips.

Maybe you have a better ear than me, which wouldn't be hard since I'm half deaf from playing music excessively loud as a lad!

 

 

That's no excuse Fran!

I've been playing drums for over 25 years and at this stage I'm deafer than most and even I can hear it!:)

Is it down to the number of cylinders per engine? I know the tsunami just offered a '645' for instance, which is anything between an 8 and 20 cylinder block. Yank outline customers were asking for specific sound recordings for each one (8, 12, 16, 20 etc)

 

Yeah I use a mixture of 12 and 16 cylinder recordings in my own locos. The number of cylinders won't make much difference to the sound though. As was said earlier it's mainly down to the higher revs of the 645.

Hi Graham, I don't know to be honest. They supply normal, tired and overhauled engine sound variations for 141s and 181s (i.e. 6 variants with PD and 6 without PD). All I know is their LokSound projects sound better than the authentic recordings made here from actual IR/IE prototypes. I've a mix of PD and non-PD LokSounds, but to be honest I prefer driving the non-PD versions, just simpler to operate. Zimo/RealDrive remains my favourite to drive but the 141/181 sound is not as good as ESU, so I've gone ESU. Jeepers we are spoiled nowadays with sound options for Irish diesel models. Noel

 

Just had a listen to the videos on the site and the engine sounds are definitely the ones from ESU. My advice if you're planning on chipping a lot of locos is to by the Lokprogrammer. You can try all of these recordings yourself and just swap them out if you don't like them.

I would imagine if PM goes to ESU for a sound decoder for the 121 (like he did with the 071 and 201) the sounds will be the same recordings.

 

The tired and overhauled engine options are also easily done. There is an option to increase the playback speed of the file by small increments which raises or lowers the pitch of the engine sound.

Thanks Graham. I've come close to getting a LokProgrammer, but getting access to Irish diesel loco horn and whistle sounds and the steep learning curve has put me off. I'd love to try 'rolling' my own sound project where one could switch from 'Full Throttle' mode to auto notching at will, and add other tracks such as rail clack nose at various speeds, brakes for an entire rake, etc. As its pure software I would hope it is possible anyway to have a project that can be switched via function from 'normal' to 'tired' engine mode on the same chip without needing to reflow it.

That's exactly what they sounded like. I remember when I started as an apprentice in Inchicore back in 1977, one of the Sulzers was ticking over on the line just across from the carriage shop. The fitters working on it would rev it every now and again. Over the next few days, that loco and other Sulzers were shunted into a siding were they remained for many years to just rust away..

Hi all I'm new to this but maybe yous can advise me .I have a full HDI..train set made in Shannon. Don't know the age but age been the issue. The locomotive is extremely slow when I couple the carriages. Was thinking would it be advisable to put new motor in the loco or leave her grow old gracefully. Thanks brassnut

Hi Brassnut.  Not sure if your query is 121 related.  I doubt she needs a new motor.  Probably just needs some minor servicing with lube and gearbox grease to free her up.  If you remove the motor temporarily and run it direct off 12v to see if its free and running smoothly, and then check if the chassis wheels are running freely.  If not clean any hardened grease off and lube axles and gears until she runs free again.  Noel

Wrong thread for this really as they’re not 121 class locos but Dave Bracken (@wrenneire) may be able to assist you.
