The TRD-2D reconstruction procedure aims at demonstrating the claim made in the TRD TDR Addendum that:
"An improved position sensitive detector is needed in the mostly exposed are of the TRD wall (most 10 inner chambers) in order to access a kinematic range (e.g. protons below 200 MeV/c at mid rapidity) with high potential of discovery."

The demonstration consists of several steps:
1. The possibility to use the tracking infrastructure of CBM to seed tracks directly from the TRD(2D) hits to cover the blind spot of the main STS-based tracker.
2. The procedure to further attach hits from the STS and ToF systems in order to estimate track kinematics and PID respectively.
3. The performances of such procedure in terms of track determination wrt the TRD-1D default solution.

Since the implementation of a full tracking scheme in CBM starting from TRD, as sketched above, involves an amount of man-power which was not available within the boundaries of the document reviewing, a simplified, back-up solution is proposed here to suggest the  realization potential of our proposal. Therefore the following steps were proposed:
1. Build track seeds directly from TRD(2D) hits, using also incomplete track detection (less than 4 hits/track) based on L1 algorithm.
2. ToF (and STS) hit attachment based on linear extrapolation of the TRD track.
3. Track momentum estimate based on track propagation to vertex (Kalman filter)
4. Proton identification based on ToF hit info and momentum.
5. Identification of local observables based on the TRD-ToF track fit sensitive to the kinematic observables rapidity (Y) and transverse momentum (pT).
