Dear Märklin friends, I'be purchased on e-bay this VB Loko. You've here some pics. i'm asking: is it normal it has only one light. in a direction it goes fluid, but in reverse the loce need to be pulled a bit on the rail. Any suggestions, please, to fix it? Best regards Prof. Stefano Rocca

Hi Stefano I looked back at my VB catalogues and no mention is made of a reverse light. VB locos like the 9001 could be fitted with one or two motors (of course having a diode in series for light change depending on direction. Here is the "exploded view" of the time (1955) showing all spares  Here are some more VB parts (most probably also valid for the 9200 loco  The loco is a sort of Maccano capable of: - 2 rails or 3 rails - 1 or 2 motors - a variety of sliders (side, central, ski slider) - power by rail or by catenary. I strongly suspect the BB 9200 inherited of most the parts used in the BB 9001 Definitely, VB locos have a very decent pulling power (my youth is filled with the sight of 2 m long VB trains so I guess you need to check a few things: - smooth rotation of all wheel and a small lubrication - good brushes on the motor as worn one may go oblique and stall the motor - check force on the brushes It must be similar to a Märklin motor brush - a good cleaning of the mechanism is in order. - inspection of the pinions for wear or abuse. VB weakness is with nylon pinions (silent, smooth but fragile) - NEVER try to rotate the motor by turning its wheels as it may damage the nylon pinions. If you are interested I can send you PDF copies of VB catalogs (need an email though) Cheers Jean |

Dear John, your help is always so precious. I'll try tomorrow all the lubrication. Is the Märklin oil good for it, as well? I've just tried to push the brushes, but coud I put on the M-rklin ones as well? I'd appreciate so much the PDF and I'm sending you in pvt my e-mail. Best regards!

Hi Stefano
VB Oil: at the time (50s) VB was selling sewing machine oil made by a French brand ANTAR.
IMO, the best is to use wintergrade oil for cars as also recommended by Märklin at that time.
Now Märklin oil is less viscous and is adapted to more precise manufacturing (small tolerances) and non-agghression of plastic parts (which you don(t have on VB except the Nylon gears
Using Märklin brushes on VB. Check the diameter and length. Material is graphite in both cases.
Märklin produces 2 different diameters for cylindrical brushes (E600300 and E600350 for large 800 series locos). Of course you must use only the graphite brush and not the mesh one
Cheers
