Note that a false rail has been used on the straight at Windsor for at least the last 6 years.
The false rail is used to split the straight approximately in half, and races then use either half of the course to relive wear of the turf.
The side of the course to be used is usually decided during the week prior to racing.  The stalls are mostly positioned High throughout, on both halves of the course.
Information by courtesy of The Clerk Of The Course 13 Apr 2006.

The use of a false rail could be a contributory factor towards spreads of results, so it may be unwise to read too much into these stats.
If we ever get an indication of false rail usage in results returns, it will be possible to produce more accurate stats.
At present with stalls High, we are looking at results of races started with the stalls next to the stands' rail, and in the Centre of the course, next to the stands' side false running rail.

On good or better going there are spreads of results throughout this chart.
Before the 2005 results were added, in races of 8-14 runners, the Top 3 stalls won 15 of 27 races 55%.
That is an excellent percentage for only 3 stalls.
The advice for 2004, 2005 and 2006 was to watch the Top 6 stalls in these races.
During 2005, on good or better going,  the Top 6 stalls won 7 of 8 races
under those conditions.
In 2006 the Top 6 stalls won 4 of 6 races.

On good or better going in races of 8-14 runners, the Top 6 stalls
won 28 of 41 races 68 %.

Historically, there has not been a draw advantage of any significance over this course and distance, so although there was good clustering in 3 stalls, and now a good percentage from the Top 6 stalls, we should not get carried away with this pattern.
Realistically, there are spreads of wins throughout most of this chart.

If we ever get an indication of false rail usage in results returns, it will be possible to produce more accurate stats.
At present, we are looking at results of races started with the stalls next to the stands' rail, and also in the Centre of the course, next to the stands' side false running rail.

On good, good to soft in places or softer going, results are spread across a wide range of stall numbers.
