Hi all i want to design a circuit which can be used to count the number of wheels in a train using IR detection.
Please help to design the same.

What do you want to do?Count them when it is moving?I mean for what?

First of all do you know how IR sensors work? You have a transmitter and a Receiver.A train travels very fast, and how would you mount a system to do this practically?Counting can be done in various ways and the best is using microcontrollers.

What size train? Is direction important? Is this out in the sunlight where IR will be an issue?

A little more detail will get you more ideas. Maybe look into laser. Will you be allowed to mount them near the track assuming a real train?

my design is like when ever a wheel passes between the IR TX and RX it will give you a pulse, this pulse will give an interrupt to the Micr0 (eg ,8051),
on the BAsis of the interrupt micro will count the no of wheel passed through a signal.

i have only one doubt hwith this whether this circuit will give me a sharp pulse which can interrupt micro?
