    Hi Paul
    The high current draw may be down to the magnets loosing thier magnetisim.
    There are replacement motors kits available for the Lima Ringfield motor based loco's.

    Lima Railcar Motor Replacement Kit

    I have one for my Lima O gauge 4F - but still need to fit it. However users who have fitted the replacement motors give very favourable reviews, and reckon the loco's are really smooth runners after the conversion.

    As Tom has stated the Heljan's do have higher current usage, but will be within the current restraints of the decoder. My Heljan DPU & Cl 26 both use 0.1A for the lights, and approx 0.4A for the loco and lights. My sound fitted Bachmann Cl 24 (ESU V4) draws approx 0.3A with lights, sound and 3 coaches behind it.

    Hope this helps

    Paul

    And I've found a video to go with it

    There is a Dapol Parcels one on the way June/July. I bought a Passenger version some months ago. It's fitted with a Zimo 'YouChoos' sound chip and I couldn't more than recommend it. It also copes with #2 radius curves no problem, something my old (now retired) Lima version was never happy with.

    I would keep both DC & DCC electrically separated at the outputs- just switching off mains power is not enough - I have seen what happens to a NCE Powercab when DC got onto the output of the NCE controller - not nice...

    Some good advice there I think. I'd be a bit edgy about mixing the two as well. Keep them well isolated unless you have deep pockets.

    Trouble with switches is there is nowhere to mount it without quite a lot of work. This is a temporary testing and DCC set up track and has no control panel! Only way I can see is to find a small plastic box , mount the switch on one side and sockets for the three sets of cables (one input, two outputs on the other and then put appropriate plugs on the three leads.
    Anyone got a suggestion involving less work?
    May have to put up with continuing to unplug the lead to the tracks from the back of my NCE control box!

    Many thanks
    Best regards
    Paul

    Then maybe use a Deans connector (male end wires connected to the track), and a female connector on the output from the DCC and another on the DC output, you then just connect the power source in use to the track. By having the female end on the power source, it won't short out if you forget to turn the power off.

    Hi All,
    It is over 3 months since my last update, apologies for the long silence!

    Thanks to Sol and Paul_I for their input on the separation of DC and DCC. I have for the moment just gone for the simple solution of trying not to change from one to the other too often, but making sure everything is appropriately isolated!

    Currently working on chipping locos, and finalizing layout plan.
    Since starting on sound chip fitting I have concluded that I will sound fit more locos than I first thought which increases the cost.
    So I am looking at using the Hornby TTS rather than £100 sound chips in a number of locos that they were not originally aimed for, such as fitting them to other manufacturers locos and to different types of loco than they were designated for.

    There are some nonos in this.
    Not a good idea to fit 2 cylinder sound in three cylinder locos or Great Western loco chips in other company locos (or vise versa!!).

    I have managed to find some Hornby chassis for my Lima bodies although sometimes I have had to buy a whole loco, but some liveries are quite cheap.
    Picking up on Splitpin's comment in May, I needed the "angular" GWR parcels car No 34, not the earlier version No 17.

    I have also replaced a couple of Hornby and Bachmann locos that were not capable of being chipped with more modern versions of them that are capable of being chipped.

    There are two things I would appreciate info on:-
    1) Did Lima fit the 5 pole motor from their 00 class 67 to any other UK outline 00 loco?
    2) Is there any Hornby TTS diesel loco chip that sounds right in an 00 first or second generation DMU?

    I will try to keep you informed of how I am getting on.
    I will aim not to be too ambitious in this after failing to keep info flowing in the past. So I hope to do a monthly update.

    Best regards
    Paul

    As far as the DC and DCC inputs are concerned, the cleanest and safest method is to have a single input to the track connected to a double pole double throw switch from the DC and DCC inputs. This will avoid the inevitable situation when you inadvertently have both power sources active. The NCE system will not like this!

    Cheers

    and happy modelling

    Hi All,
    Well technically it is still October, so it is only some 6 weeks since my last update, but doing one every 4 weeks or so is harder than it sounds!

    So where am I now?
    Chipping of locos is proceeding steadily and with more TTS chips coming out I have more variety in my locos:-
    I have britannia chips in a Britannia, and also in a 73xxx. The J36 chip has gone into an Ivatt small 2-6-0 (465xx) and a 76xxx standard.

    I have found someone to chip my Lima diesels and am awaiting the return of the first batch. Chipping HSTs has involved replacing the motors, and fitting pickups to the dummy cars, so I will tell you about the results next time.
    I also have found some Loksound 3.5s and am awaiting their fitment into appropriate Diesels and multiple units.

    Having about bottomed out the model track layout I am working on the signaling plan which is colour lights for the mainline and semaphores for the branch. Strictly this dates the layout to post the WR mainline 1963 resignalling, whereas I am timing it as mid 1962. However this compromise makes it possible to run the 1992 version of the layout with just the semaphores changed for colour lights.

    I am investigating computerizing the layout via a Roco Z21 and I train on a old iPhone with a mimic diagram on an older Ipad.

    I am also investigating the Soundtraxx modules as a way to chip some locos not available via TTS.

    So lots to update you on in the November posting!

    Happy modelling
    Regards
    Paul
