Veteran motordræsine eller inspektionsbil bygget i 1920'erne af:
| Fremdrift: | En 2- cylindret luftkølet totaktmotor 5-6 HK. |
| Bremse: | Pedal der påvirker en tromle med bremsebånd på bagakslen. |
| Håndbremse: | Aktiverer bremsesko på begge forhjul. |
| Transmission: | Baghjulstrukket via langsgående motoraksel og differentiale. Hjuldiameter ca. 46 cm, akselafstand ca. 1,25 m. |
| Kontroller: | To-delt kabeltræk fra kabinen (formentlig gashåndtag og gear). |

Inspektionsbil - kaldt ”ildflue” fra 1928. Brugt af overbanemesteren i Ryomgård til kontrol af jernbane og sporskifter.
2- cylindret luftkølet totaktmotor. 5-6 HK. Ingen bakgear! Hastighed 45-50 km/t. Når køretøjet skal den modsatte vej, løftes det ved hjælp af en centralt placeret donkraft, og drejes 180 grader. |
4 hjul og en motor, med en meget spinkel "kabine" udstyret med et havebænk-agtig dobbelsæde. Det er givet at prisen har spillet en større rolle end hensynet til bekvemmelighed og sikkerhed. Det må have været ret irriterende at skulle af og enten vende maskinen eller skubbe, for at bakke ind på et sidespor.
Ildfluen var, også for sin tid, et primitivt køretøj. I Danmark var der næsten 89.000 automobiler i 1928, en del var Ford-T modeller som der var produceret næsten 15 millioner af, fra 1908 til 1928. - Så bakgearet var altså opfundet.
Modellen
Modellen er fremstillet efter billeder taget af CaBrag på Danmarks Jernbanemuseum i Odense. - Tak for hjælpen Carl !
Odenses Ildflue har tilsyneladende røde lygter både for og bag, medens overbanemesteren fra Djursland havde en
forlygte.
Jeg har tillad mig også at udstyre modellen med klart lys fremad, dog er der ikke meget af det.
Jeg har ingen oplysning om vægt, men gætter på 2-300 Kg. Det forekommer at 5Hk må have kunnet give den en noget større hastighed end de 50 Km/t. Modellen er blevet lidt hurtigere.
Selvom den intet bakgear havde, har jeg alligevel lavet mulighed for at den kan køre baglæns.

Motordraisine eller inspektion vehicle build in the 1920'ties by:
| Propulsion: | A 2-cylinder air-cooled two-stroke engine. 5-6 HP. |
| Breakes: | Pedal activating a braking drum on the rear axle. |
| Handbreake: | Breakes both front wheels. |
| Transmission: | Driving read axle via a differential. Wheeldiameter ca. 46 cm, axle distance ca. 1,25 m. |
| Controller: | Two cables from the cabin (probably speed and gear). |

Inspections vehicle - called ”firefly” from 1928. Used by the railroad technical manager in Ryomgård.
2-cylinder air-cooled two-stroke engine. 5-6 HP. No reverse gear! Max speed 45-50 km / h When the vehicle need to go in the opposite direction, it is lifted by means of a centrally positioned jack, and is rotated by 180 degrees. |
4 wheels and an engine with a very tenuous "cabin" features a garden bench-like double seat. This shows that the price must have played a greater role than considerations of convenience and safety. It must have been quite annoying to have to either turn the machine around or push it backwards.
Firefly was a primitive vehicle. In Denmark, there were nearly 89,000 cars in 1928, part was Ford T models which were produced almost 15 million of from 1908 to 1928. - The reverse gear had been invented long ago.
The model
The model is mainly based upon pictures taken by Carl Poul Brager at Denmarks Jernbanemuseum in Odense. - Thank you for the help Carl !
The firefly from Odense seems to have red ligths in both ends, the one from Djursland had a white front light.
I have given it a white front light, but not much.
I have no information on weight, but guess 2-300 Kg. It seems to mee that 5hp should have been able to give it a somewhat higher rate than the 50 km/h The model was made a little faster.
Although it had no reverse gear, I still made it possible for it to run backwards.
