Hello.
An approach for significant improvement of electric pickup is described.
This idea can be used for improving pickup for other locos.
EXPLANATION:
-BR232 has 6 axles.
-Two middle axles havent any contact with rails, and are flying under rail at height about 0.3mm.
-Two of remaining 4 axles have traction tires.
-Therefore, we have only 2 axles for current pickup.
- This quantity cannot guarantee uninterruptable run at slow speeds for N-scale .
-4 or more current pickuped axles needed for dependable run.
-All wheels must touch rails for any curved track . This property will improove as current pickup as well as pulling force.
IDEA:
-The main idea consists on springing every axle and adding backlash.
Also:
- Another electrical-friction contacts between trucks and body replaced by thin flexible wires.
- Electronic FlyWheel added
- Additional weight added.
- Motor lights added
STAGES:
1) Drill backlash under the axle's bearings:

2) Polish wheel's flanges:

3) Solder 12 thin stripe-shaped springs with ortophospic acid flux:

4) Solder trucks to body by thin flexible wires with silk fiber (From Nokia HandSet for example)

5) Insert wheels:

6) Middle placement of traction tires give us more stable truck's movement and larger pulling force

7) Insert and solder Electronic FlyWheel or Power Pack.(Simply, it's a capacitor about 1000mkf) Solder it to Power Pads of Decoder according Zimo MX620 manual. U Can use SUSI power pads also, or Lenz Power Pack pads.

8) Add additional PlumBum weights

9) Add 2 SMD LEDS under Motor:

May be these ideas can help somebody.

Hi Vadim
Thanx for the hints.
The main problem seems to create and fit and solder the thin stripe-shaped springs.
I love locos with as much connected wheels as possible.png)

Thank for answer, Thomas!
I like the same!
I use locos with real braking and accelerating speeds.
(Real Loco can start from station about 2 minutes)
This is very small speeds, needing extreme electric pickup!
One part - Extreme pickup from locos
Second part - Extra sterile rails. (Simply - NEWER TOUCH IT BY HANDS and clean by sterile Alcohol)
Also i use digitized Tomix Vacuumer and swab car
As to springs:
-These springs You can get from magnetic stripes which defend goods in stores.
Also, A lot of these springs You can get from some old CD, HDD computer devices (especially 386, 286 and earlier).

IN ADDITION:
There are two DEMONSTRATIONS HOW IT WORKS:

Thanks, Bjorn.
Thomas, metallic, ferum containing flexible springs can be easy soldered by OrthoPosphoric acid.
-You must carefully clamp the locomotive with opened truck without wheels at grip.
-Then You take a smal drop of this acid and place into edge of spring.
-Then You take spring by very small tweezers with clamp, and precisely present it into old truck's pickup vertical springs (see picture).
- Please remain some backlash for spring's end motion.
-Then You take a very small soldering iron, take by this iron a small droplet of solder alloy and shortly (1 second) touch both springs in place of acid drop.
- OrtoPhosporic acid works very well and serve as best flux.
-No other flux needed in this operation.
- All truck must be washed well by water after all solderings in aim to avoid following degradation by remaining acid.
- The better thing - do this operation when trucks are disassembled out of locomotive.
HINT:
-For better attachment of old splings being soldered, You can drill in horisontal plane of truck a small drillings near attachment this springs to plastic: 4 drillings per truck, (one per edge).
-Then, You can pass through this drilling a thin metallic wire (cutted arm of any radioelement, resistor , for ex.) Then You can solder 3 things together at one time. Described drillings must be at 45 deg at the vector of motion. This makes more durability of this joint.

POWER PACK DEMONSTATION:
There are 3 small Clips:
1) Non-modified loco WITHOUT POWER PACK goes through insulation from powered to unpowered rail.
Please, make an attention ( focuse ) on distance between powered rail and stopped last wheel at the end of clip. (This is a free flying distance )
VIDEO: http://www.youtube.com/watch?v=4Px11yvQjQ4
2)DCC N-Scale Loco WITH POWER PACK cap (1000mkf * 16V) goes through insulation from powered to unpowered rail. Please, also make an attention (focuse) on distance between gap and stopped last wheel at the end of clip. This is a free flying distance which give to loco a potential of riding over nonconductive dusts.For details and for scheets how to solder power pack see : http://www.zimo.at/web2007/pdf/MX620MX63MX64E.pdf (page 37)
VIDEO: http://www.youtube.com/watch?v=6yQkIB_MsfI
3)Three DCC N-Scale locos are riding at slow speed and reacts on moment of DCC voltage shutdown .
See the difference between LED lights fading at the end of clip.
1) Green usual loco (Brava BR232)
2) Red Roco BR101 with power pack cap = 220mkf * 16V
3) Red Brava BR232 with power pack cap = 1000mkf *16V
Slower fading tell us about greater stored power which increase free flying distance at unpowered (or dusted) rails.
