The Class 424 steamer, the pride of MÁV.
She was developed after the WW1.
The large Hungarian clearances allowed to build a steam locomotive
with firebox fully above the drivers.
With their 63" drivers the Class 424 locos were universal engines.
They hauled passenger trains and freight trains,
and sometimes even express trains.
They were extremely efficient,
consumed almost 10% less coal than the other passenger engines.
They were built in three lots, a few in the 1920s,
many during the WW2 and the third lot in the mid. '50s.
Several of them were exported to Slovakia
and were built as war reparation for Yugoslavia and Soviet Union.
Many of them were built for North-Korea during the Korean war.
This picture shows the 424,005 on plinth at the Budapest-Rákospalota station.
Since the photo was taken in 1990, this engine has been removed and disappeared.
I was very happy to see it again on December 2nd, 2004
on the yard of the Istvántelke Workshop.
The front of 424,005. The smoke deflectors were mounted in the '50s. The
424,005 was rebuilt with new boiler and dual stack, as most of the Class
424 engines.
The 424,009, member of the MÁV "Nostalgia" stock.
This engine was rebuilt into its original form, with single stack,
removed smoke deflectors and screwed smokebox-door.
The photo was taken on the locomotive show on 7th July 1993 in Budapest.

The 424,262, member of the MÁV "Nostalgia" stock.
This engine was built in 1956, among the last Class 424s.
It is in its original form now.
The 424,262. It has been rebuilt to oil fired firebox,
and is oil version today too.
There is a third Class 424 in the MÁV "Nostalgia" stock,
the 424,282. She is a late coal fired engine.
The valve gear of 424,005.
Look at the rather unusual boxlike shape of the reverse link.
