Smallest T-Gauge loco?

[Lynbarn]

I have a dream. It is to build a model of Southend Pier Railway. The railway was a simple, straight, dual track, with two scissors crossovers, and a simple two-platform station at either end. The pier is about 1.3 miles long. The model I want to build is of the 1949 electric stock (see https://en.wikipedia.org/wiki/File:0030 ... _pier2.JPG) These ran on 3'6" (1.06m) gauge track with a central third rail (I might dispense with that detail!) and each of the four trains had 7 coaches (three motorised) each 29'6" (9m) long. In 1:450 scale, these work out at 20mm long (and 4.40mm wide, 5.24mm high).

Does anybody have any ideas on obtaining a T-Gauge loco that small? (I did think maybe two or more units could be articulated, with a flexible drive between them, to separate motor and gearbox). Any ideas/suggestions/comments?

An alternative would be to build using Z-gauge, but that would make the layout rather too long for me to exhibit easily.

Thanks in Anticipation,

Martyn

Love the idea and have thought about it a lot myself being an essex lad!
I don't think youd get one that short but you could always combine 2 coaches as 40mm is more realistic. On the long straights and even the crossings you will probably get away with it with a superficial bogey underneath in the centre

Hi, great idea. You are lucky in that your subject is dead straight, this means that if you want you can easily use an alternative form of propulsion; as there is a slot between the decking boards and the rails you could for example have a threaded rod (M4) with a nut on it which has a short length of wire attached under the base board. The wire protrudes through the slot and as the rod is turned the wire/nut moves back or forth pushing/pulling your train!!! Or some VERY fine thread laying between the rails that returns on its self under the base board!!! Cheep and easy but maybe not what you're looking for ?
Great project. I wish you all the best.

As soon as someone cracks this problem by producing a micro-mini powered unit, then I'll be in like a rocket. It'll be ideal for producing 1st generation trams.

Like these examples that ran in Glasgow:

As far as Smallest T-gauge locomotive made happen appears to be the BR70 by Uwe Fenk:

Of course, his stuff all scratch build for the most part. He did appear to introduce the first worm drive into T Gauge though.

Hello, the Class 70 is no longer the smallest steam locomotive, the D VI is even smaller!

Hello Martyn, that's relatively easy to build (look photos).

As gears between the wheels take which with 20 teeth.

Uwe, do you have the dimensions of the PCB-46495-002 motor?

Thanks!
Jesse

[MMBUFBerlin]

Hello Jesse, the case of this motor has the dimensions 3x4x6mm.

Important Note: The gears with 20 teeth are only usable if your layouts are WITHOUT points/turnouts and crossings !!

[MMBUFBerlin]

A new smallest T Gauge loco is in work. Only 11.5mm long!

[MMBUFBerlin]

It takes shape.

This is great. Can we expect a cool video as well?

[MMBUFBerlin]

No, it's small! (-;
So small that it is very difficult to make a sharp video. Also drives a locomotive with only two axles and small wheels not as good as steam locomotives with large wheels.

Great job. Congratulations.

Thank you, Pawel.
Just a little video to demonstrate that the little locomotive really drives:
