H0f gauge
From Wikipedia, the free encyclopedia
H0f gauge, occasional as H0i[1] gauge designated, is a rail transport modelling scale representing Feldbahn-style 2 ft and 600 mm gauge railways using 1:87 HO scale running on Z gauge 6.5-millimetre (0.26 in) track.[2] The Normen Europäischer Modellbahnen NEM 010 specification defines H0f for modelling gauges 400–650 millimetres (16–26 in), as part of the 1:87-scale family that includes narrow-gauge railway models using H0e gauge and metre-gauge railway models using H0m gauge.[1]

Rolling stock
As of 2007[update] three variants of the Babelsberg LKM Ns2f, along with tipper and flat wagons, were being manufactured by Technomodell, plus left-and-right-hand points, and flexi-track using 2.1 mm-high (0.083 in) rail.[3] The NS2f models were completely metal in order to improve traction and allow gradients of three-percent to be negotiated with wagens.[3] The NS2F chassis is 30 millimetres (1.2 in) long, and the locomotive body 38 millimetres (1.5 in) long.[4]
In 2008 the company Panier were producing a model of the Lanz-Rail tractor in H0f gauge,[5] and Präzisionsmodellbau were producing the LKM V10c (de) and Ns4f.[5]
For the fiftieth-anniversary of the Saarbrücken Park Railway (de) in 2010, a model of the "Porschelok" (de) and matching carriages were produced in H0f.[6]
Busch Feldbahn
H0f track and locomotives made by the German company Busch include a central magnetic strip hidden between the rails for greater adhesion.[2] The magnet under the Busch H0f locomotives is extremely effective, allowing very steep gradients, climbing vertically,[7] or running upside down.[8]
The first Busch Mine Railway Starter Set (Grubenbahn Start-Set) was released in late-2010 and featured a BBA B360 mining locomotive (de) with three wagons,[9] based on those at the Erzbahn in Schönborn-Dreiwerden, north of Chemnitz. The set came with 145-millimetre (5.7 in) radius Z scale track with 1:220 sleepers, and a separate rectangular metal base plate underlay for magnetic adhesion.[9] The mining system was expanded with four more sets in 2011.[10]
A much larger system of narrow gauge locomotives was introduced at the 2012 Nuremberg International Toy Fair, where Busch demonstrated a complete Feldbahn system with multiple locomotives wagons and specialist track.[11] Models of a Gmeinder 15/18 horsepower locomotive were supplied to journalists and partners.[11]
By the start of 2016 Busch was producing a Deutz OMZ 122f locomotive in three colours.[12] At the 2016 Nuremberg International Toy Fair, an unpowered Lanz traktor model accompanied by a motorised goods van were shown, along with a Decauville Type 3 steam locomotive.[13] One year late in 2017 a model of the Frankfurt Feldbahn Museum's (de) steam locomotive Dimitrias was shown.[14] The separate firm Modellbau Luft started to make alternative locomotive and "ghost wagon" housings for mounting on the Busch Feldbahn chassis.[15]
Track
Commodity Z gauge track is the correct gauge, although the sleeper style and sleeper spacing are the wrong scale for H0f modelling:

Three-rail flexi-track made for H0/H0e (16.5 mm + 9 mm) can be used because the third gauge is ~6.5 mm, but with full-size 1:87 sleepers.

In North American, HOn2 gauge is specified for representing 2 ft and 600 mm gauge railways using 1:87.1 HO scale running on 7.06-millimetre (0.278 in) track. The NMRA S-3.2 specification defines HOn2 as part of the 1:87.1-scale family.[17]
