Re: Hornby Class 20 TTS Loco in Consist

If you want to operate a pair of 20s always locked in a consist then consider having one as a dummy car (demotored) which will still take a (TTS) sound decoder and can be operated as an individual or a pair depending upon if addressed same or unlike.
Hornbys Class 43 HSTs work well so rigged.

Re: Hornby TTS - Valenta or MTU?

oooh I didn't know that! IIRC the midland main line HSTs are VP185 fitted, all the rest have MTUs Andrew Coles book is worth a read. It doesn’t take long to soak in the text as its mostly pictures, running number by number. I got mine through WH Smith online delivered to my local shop inside a week...

Re: Hornby TTS - Valenta or MTU?

Just check the road number, MTU re-engined HSTs carried +200 numbers, eg 43100 = 43300, etc. There were a few that had Mirlees engines. Some liveries were only seen with certain engines. Rob When you say Mirlees, are you referring to the VP185 engines? My book says four of the fleet were experiment...

Re: Decoder/controller incompatibility

It may be that the decoder does not like pulse stretching - a common problem with cheap decoders. Try making sure that loco 10 (the DC loco) on the E-Z Command is set to stop. The E-Z Command is a good command station for what it is and is most unlikely to be the cause of the problem - just showing...

Re: Hornby elite

Twin flex used for things like mains table lamps is OK. It is rated for more than the output of the Elite, which uses a 4-amp power pack but only 3-amps gets to the track as 1-amp is hived off for the Aux output. Folk have used twin bell wire but it would be marginal for feeding a power hungry layou...

Re: Steam loco or space rocket ?

Over the years folk have tried different motor/gear combinations but the most successful and most involved was the introduction of an intermediate gear with the motor raised horizontal to suit, the whole mounted on a new plasticard fabricated assembly.
On the RM Web forums somewhere.

Re: Hornby Class 20 TTS Loco in Consist

Added a third 5ohm resistor to the Lima Class 20 network today hoping to reduce the motor voltage even further, and reduce the speed to that of the Hornby Class 20. Odd thing, Lima is now 10% faster up to the mid speed point, and from that point the Hornby becomes progressively faster. Bu##er! Have...

Re: Decoder/controller incompatibility

History records if you ask Hattons why it doesnt work its likely they will say its Hornby’s fault. This can be seen in many places on the forums as their reported answer to many complaints about their own brand stuff not working. Strange attitude when they flog so much Hornby kit. I agree with previ...

Re: Daisy chain 2 Hornby Elites via Expressnet port

Split your bus into track and points. Run the locos from one Elite and the points from the other Elite. However the Elite is a cumbersome beast for operating points - too many button presses required, but in conjunction with software such as Rocrail, JMRI, Railmaster, etc it would just be acting as ...

Re: Hornby Lights with Guagemaster Power Supply

String the lamps in series on the 16v supply until they are of suitable brightness, then string more rows in parallel at that series number until the power supply current limit is reached. Remember incandescent bulbs vary their resistance as they heat up so you can’t really meter their values for st...

Re: Hornby Class 20 TTS Loco in Consist

The TTS decoder needs to be connected to the motor as it relies on the bemf to alter the sounds depending on load and speed, that won't happen if you use a different decoder to power the motor. TTS steamers use BEMF to control the chuff rate and chuff/coast relationship hence require a motor, but T...
