This is a passenger train that goes via the longer PBH route to reach Allahabad/Prayagraj. It starts before the ICE and reaches after it; hence only intervening station passengers board it.
The last image shows tracks coming from Transport Nagar in Lucknow. It is currently a freight only track/station but is being developed so that trains can bypass Lucknow NR when coming from Utratia Jn and going towards Moradabad side.
